BACKPORT: f2fs: invalidate meta pages only for post_read required inode
After commit e3b49ea36802 ("f2fs: invalidate META_MAPPING before
IPU/DIO write"), invalidate_mapping_pages() will be called to
avoid race condition in between IPU/DIO and readahead for GC.
However, readahead flow is only used for post_read required inode,
so this patch adds check condition to avoids unnecessary page cache
invalidating for non-post_read inode.

BACKPORT: f2fs: handle decompress only post processing in softirq
Now decompression is being handled in workqueue and it makes read I/O latency non-deterministic, because of the non-deterministic scheduling nature of workqueues. So, I made it handled in softirq context only if possible, not in low memory devices, since this modification will maintain decompresion related memory a little longer.

f2fs: support direct I/O with fscrypt using blk-crypto
Encrypted files traditionally haven't supported DIO, due to the need to encrypt/decrypt the data. However, when the encryption is implemented using inline encryption (blk-crypto) instead of the traditional filesystem-layer encryption, it is straightforward to support DIO. Therefore, make f2fs support DIO on files that are using inline encryption. Since f2fs uses iomap for DIO, and fscrypt support was already added to iomap DIO, this just requires two small changes: - Let DIO proceed when supported, by checking fscrypt_dio_supported() instead of assuming that encrypted files never support DIO. - In f2fs_iomap_begin(), use fscrypt_limit_io_blocks() to limit the length of the mapping in the rare case where a DUN discontiguity occurs in the middle of an extent. The iomap DIO implementation requires this, since it assumes that it can submit a bio covering (up to) the whole mapping, without checking fscrypt constraints itself.

f2fs rw_semaphores work better if writers can starve readers, especially for the checkpoint thread, because writers are strictly more important than reader threads.

ANDROID: f2fs: fix fscrypt direct I/O support
The upstream change to make f2fs use iomap for direct I/O was backported
to this kernel branch, which broke the out-of-tree support for fscrypt
direct I/O because f2fs_iomap_begin() isn't aware of encryption. Make
the needed change to f2fs_iomap_begin(), matching what I've proposed
upstream at
https://lore.kernel.org/r/20220120071215.123274-5-ebiggers@kernel.org.
Also drop the fscrypt support from fs/direct-io.c, which is no longer
used since both ext4 and f2fs now use iomap for direct I/O.

f2fs: move f2fs to use reader-unfair rwsems
f2fs rw_semaphores work better if writers can starve readers, especially for the checkpoint thread, because writers are strictly more important than reader threads. This prevents significant priority inversion between low-priority readers that blocked while trying to acquire the read lock and a second acquisition of the write lock that might be blocking high priority work.

f2fs: don't drop compressed page cache in .{invalidate,release}page
For compressed inode, in .{invalidate,release}page, we will call
f2fs_invalidate_compress_pages() to drop all compressed page cache of
current inode.
But we don't need to drop compressed page cache synchronously in
.invalidatepage, because, all trancation paths of compressed physical
block has been covered with f2fs_invalidate_compress_page().
And also we don't need to drop compressed page cache synchronously
in .releasepage, because, if there is out-of-memory, we can count
on page cache reclaim on sbi->compress_inode.
BTW, this patch may fix the issue reported below:

f2fs: do not bother checkpoint by f2fs_get_node_info
This patch tries to mitigate lock contention between f2fs_write_checkpoint and f2fs_get_node_info along with nat_tree_lock. The idea is, if checkpoint is currently running, other threads that try to grab nat_tree_lock would be better to wait for checkpoint. Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org> |

f2fs: use iomap for direct I/O
Make f2fs_file_read_iter() and f2fs_file_write_iter() use the iomap direct I/O implementation instead of the fs/direct-io.c one. The iomap implementation is more efficient, and it also avoids the need to add new features and optimizations to the old implementation. This new implementation also eliminates the need for f2fs to hook bio submission and completion and to allocate memory per-bio. This is because it's possible to correctly update f2fs's in-flight DIO counters using __iomap_dio_rw() in combination with an implementation of iomap_dio_ops::end_io() (as suggested by Christoph Hellwig). When possible, this new implementation preserves existing f2fs behavior such as the conditions for falling back to buffered I/O. This patch has been tested with xfstests by running 'gce-xfstests -c f2fs -g auto -X generic/017' with and without this patch; no regressions were seen. (Some tests fail both before and after. generic/017 hangs both before and after, so it had to be excluded.)

f2fs: do not expose unwritten blocks to user by DIO
DIO preallocates physical blocks before writing data, but if an error occurrs or power-cut happens, we can see block contents from the disk. This patch tries to fix it by 1) turning to buffered writes for DIO into holes, 2) truncating unwritten blocks from error or power-cut. Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org> |

f2fs_write_begin() assumes that all blocks were preallocated by

f2fs: invalidate META_MAPPING before IPU/DIO write
Encrypted pages during GC are read and cached in META_MAPPING.
However, due to cached pages in META_MAPPING, there is an issue where
newly written pages are lost by IPU or DIO writes.

On the stability side, we've found two memory leakage cases in the error path in compression flow. And, we've also fixed various corner cases in fiemap, quota, checkpoint=disable, zstd, and so on. Enhancements: - avoid long checkpoint latency by releasing nat_tree_lock - collect and show iostats periodically - support extent_cache for compressed files - add a sysfs entry to manage ra_size given fadvise(POSIX_FADV_SEQUENTIAL) - report f2fs GC status via sysfs - add discard_unit=%s in mount option to handle zoned device Bug fixes: - fix two memory leakages when an error happens in the compressed IO flow - fix commpress_cache to get the right LBA - fix fiemap to deal with compressed case correctly - fix wrong EIO returns due to SBI_NEED_FSCK - fix missing writes when enabling checkpoint back - fix quota deadlock - fix zstd level mount option In addition to the above major updates, we've cleaned up several code paths such as dio, unnecessary operations, debugfs/f2fs/status, sanity check, and typos" * tag 'f2fs-for-5.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs: (46 commits) f2fs: should put a page beyond EOF when preparing a write f2fs: deallocate compressed pages when error happens f2fs: enable realtime discard iff device supports discard f2fs: guarantee to write dirty data when enabling checkpoint back f2fs: fix to unmap pages from userspace process in punch_hole() f2fs: fix unexpected ENOENT comes from f2fs_map_blocks() f2fs: fix to account missing .skipped_gc_rwsem f2fs: adjust unlock order for cleanup f2fs: Don't create discard thread when device doesn't support realtime discard f2fs: rebuild nat_bits during umount f2fs: introduce periodic iostat io latency traces f2fs: separate out iostat feature f2fs: compress: do sanity check on cluster f2fs: fix description about main_blkaddr node f2fs: convert S_IRUGO to 0444 f2fs: fix to keep compatibility of fault injection interface f2fs: support fault injection for f2fs_kmem_cache_alloc() f2fs: compress: allow write compress released file after truncate to zero f2fs: correct comment in segment.h f2fs: improve sbi status info in debugfs/f2fs/status ... |

f2fs: should put a page beyond EOF when preparing a write
The prepare_compress_overwrite() gets/locks a page to prepare a read, and calls
f2fs_read_multi_pages() which checks EOF first. If there's any page beyond EOF,
we unlock the page and set cc->rpages[i] = NULL, which we can't put the page
anymore. This makes page leak, so let's fix by putting that page.

f2fs: fix unexpected ENOENT comes from f2fs_map_blocks()
In below path, it will return ENOENT if filesystem is shutdown:
- f2fs_map_blocks
- f2fs_get_dnode_of_data
- f2fs_get_node_page
- __get_node_page
- read_node_page
- is_sbi_flag_set(sbi, SBI_IS_SHUTDOWN)
return -ENOENT
- force return value from ENOENT to 0
It should be fine for read case, since it indicates a hole condition,
and caller could use .m_next_pgofs to skip the hole and continue the
lookup.
However it may cause confusing for write case, since leaving a hole
there, and said nothing was wrong doesn't help.
There is at least one case from dax_iomap_actor() will complain that,
so fix this in prior to supporting dax in f2fs.

f2fs: introduce periodic iostat io latency traces
Whenever we notice some sluggish issues on our machines, we are always curious about how well all types of I/O in the f2fs filesystem are handled. But, it's hard to get this kind of real data. First of all, we need to reproduce the issue while turning on the profiling tool like blktrace, but the issue doesn't happen again easily. Second, with the intervention of any tools, the overall timing of the issue will be slightly changed and it sometimes makes us hard to figure it out. So, I added the feature printing out IO latency statistics tracepoint events, which are minimal things to understand filesystem's I/O related behaviors, into F2FS_IOSTAT kernel config. With "iostat_enable" sysfs node on, we can get this statistics info in a periodic way and it would cause the least overhead.

f2fs: extent cache: support unaligned extent
Compressed inode may suffer read performance issue due to it can not use extent cache, so I propose to add this unaligned extent support to improve it. Currently, it only works in readonly format f2fs image. Unaligned extent: in one compressed cluster, physical block number will be less than logical block number, so we add an extra physical block length in extent info in order to indicate such extent status. The idea is if one whole cluster blocks are contiguous physically, once its mapping info was readed at first time, we will cache an unaligned (or aligned) extent info entry in extent cache, it expects that the mapping info will be hitted when rereading cluster. Merge policy: - Aligned extents can be merged. - Aligned extent and unaligned extent can not be merged. Signed-off-by: Chao Yu <chao@kernel.org> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org> |

When we print out a discontinuous compression chunk, it shows like a continuous chunk now. To show it more correctly, I've changed the way of printing fiemap info like below. Plus, eliminated NEW_ADDR(-1) in fiemap info, since it is not in fiemap user api manual. Let's assume 16KB compression cluster. <before> Logical Physical Length Flags 0: 0000000000000000 00000002c091f000 0000000000004000 1008 1: 0000000000004000 00000002c0920000 0000000000004000 1008 ... 9: 0000000000034000 0000000f8c623000 0000000000004000 1008 10: 0000000000038000 000000101a6eb000 0000000000004000 1008 <after> 0: 0000000000000000 00000002c091f000 0000000000004000 1008 1: 0000000000004000 00000002c0920000 0000000000004000 1008 ... 9: 0000000000034000 0000000f8c623000 0000000000001000 1008 10: 0000000000035000 000000101a6ea000 0000000000003000 1008 11: 0000000000038000 000000101a6eb000 0000000000002000 1008 12: 000000000003a000 00000002c3544000 0000000000002000 1008 Flags 0x1000 => FIEMAP_EXTENT_MERGED 0x0008 => FIEMAP_EXTENT_ENCODED Signed-off-by: Daeho Jeong <daehojeong@google.com> Tested-by: Eric Biggers <ebiggers@google.com> Reviewed-by: Chao Yu <chao@kernel.org> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org> |

f2fs: compress: remove unneeded read when rewrite whole cluster
when we overwrite the whole page in cluster, we don't need read original data before write, because after write_end(), writepages() can help to load left data in that cluster.

f2fs: remove allow_outplace_dio()
We can just check f2fs_lfs_mode() directly. The block_unaligned_IO() check is redundant because in LFS mode, f2fs doesn't do direct I/O writes that aren't block-aligned (due to f2fs_force_buffered_io() returning true in this case, triggering the fallback to buffered I/O).

f2fs: make f2fs_write_failed() take struct inode
Make f2fs_write_failed() take a 'struct inode' directly rather than a 'struct address_space', as this simplifies it slightly. Signed-off-by: Eric Biggers <ebiggers@google.com> Reviewed-by: Chao Yu <chao@kernel.org> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org> |

f2fs: let's keep writing IOs on SBI_NEED_FSCK
SBI_NEED_FSCK is an indicator that fsck.f2fs needs to be triggered, so it
is not fully critical to stop any IO writes. So, let's allow to write data
instead of reporting EIO forever given SBI_NEED_FSCK, but do keep OPU.
