Pull f2fs update from Jaegeuk Kim: "In this round, we've mainly focused on performance tuning and critical bug fixes occurred in low-end devices. Sheng Yong introduced lost_found feature to keep missing files during recovery instead of thrashing them. We're preparing coming fsverity implementation. And, we've got more features to communicate with users for better performance. In low-end devices, some memory-related issues were fixed, and subtle race condtions and corner cases were addressed as well. Enhancements: - large nat bitmaps for more free node ids - add three block allocation policies to pass down write hints given by user - expose extension list to user and introduce hot file extension - tune small devices seamlessly for low-end devices - set readdir_ra by default - give more resources under gc_urgent mode regarding to discard and cleaning - introduce fsync_mode to enforce posix or not - nowait aio support - add lost_found feature to keep dangling inodes - reserve bits for future fsverity feature - add test_dummy_encryption for FBE Bug fixes: - don't use highmem for dentry pages - align memory boundary for bitops - truncate preallocated blocks in write errors - guarantee i_times on fsync call - clear CP_TRIMMED_FLAG correctly - prevent node chain loop during recovery - avoid data race between atomic write and background cleaning - avoid unnecessary selinux violation warnings on resgid option - GFP_NOFS to avoid deadlock in quota and read paths - fix f2fs_skip_inode_update to allow i_size recovery In addition to the above, there are several minor bug fixes and clean-ups" Cherry-pick from origin/upstream-f2fs-stable-linux-4.9.y:ac389af190f2fs: remain written times to update inode during fsync270deeb871f2fs: make assignment of t->dentry_bitmap more readablea4fa11c8daf2fs: truncate preallocated blocks in error case4478970f0ef2fs: fix a wrong condition in f2fs_skip_inode_update29cead58f5f2fs: reserve bits for fs-verity848b293a5df2fs: Add a segment type check in inplace write2dc8f5a3a6f2fs: no need to initialize zero value for GFP_F2FS_ZERO83b9bb95a6f2fs: don't track new nat entry in nat seta33ce03ac4f2fs: clean up with F2FS_BLK_ALIGNa3f8ec8082f2fs: check blkaddr more accuratly before issue a bio034f11eadbf2fs: Set GF_NOFS in read_cache_page_gfp while doing f2fs_quota_readaa5bcfd8f4f2fs: introduce a new mount option test_dummy_encryption9b880fe6e6f2fs: introduce F2FS_FEATURE_LOST_FOUND feature80d6489a08f2fs: release locks before return in f2fs_ioc_gc_range()9f1896c490f2fs: align memory boundary for bitopsc7930ee883f2fs: remove unneeded set_cold_node()355d234640f2fs: add nowait aio supporte9a50e6b94f2fs: wrap all options with f2fs_sb_info.mount_optb6d2ec83e0f2fs: Don't overwrite all types of node to keep node chain9a95481629f2fs: introduce mount option for fsync mode4ce4eb6970f2fs: fix to restore old mount option in ->remount_fs8f711c344ef2fs: wrap sb_rdonly with f2fs_readonlyc07478ee84f2fs: avoid selinux denial on CAP_SYS_RESOURCEac734c416ff2fs: support hot file extensionf4f10221acf2fs: fix to avoid race in between atomic write and background GCe87b13ec16f2fs: do gc in greedy mode for whole range if gc_urgent mode is sete9878588def2fs: issue discard aggressively in the gc_urgent modead3ce479e6f2fs: set readdir_ra by default5aae2026bbf2fs: add auto tuning for small devices78c1fc2d8ff2fs: add mount option for segment allocation policyecd02f5646f2fs: don't stop GC if GC is contended1e72cb27d2f2fs: expose extension_list sysfs entry061839d178f2fs: fix to set KEEP_SIZE bit in f2fs_zero_range4951ebcbc4f2fs: introduce sb_lock to make encrypt pwsalt update exclusive939f6be042f2fs: remove redundant initialization of pointer 'p'39bea4bc8ef2fs: flush cp pack except cp pack 2 page at first770611eb2af2fs: clean up f2fs_sb_has_xxx functions4d8e4a8965f2fs: remove redundant check of page type when submit bioe9878588def2fs: issue discard aggressively in the gc_urgent modead3ce479e6f2fs: set readdir_ra by default5aae2026bbf2fs: add auto tuning for small devices78c1fc2d8ff2fs: add mount option for segment allocation policyecd02f5646f2fs: don't stop GC if GC is contended1e72cb27d2f2fs: expose extension_list sysfs entry061839d178f2fs: fix to set KEEP_SIZE bit in f2fs_zero_range4951ebcbc4f2fs: introduce sb_lock to make encrypt pwsalt update exclusive939f6be042f2fs: remove redundant initialization of pointer 'p'39bea4bc8ef2fs: flush cp pack except cp pack 2 page at first770611eb2af2fs: clean up f2fs_sb_has_xxx functions4d8e4a8965f2fs: remove redundant check of page type when submit biob57a37f01ff2fs: fix to handle looped node chain during recovery9ac5b8c540f2fs: handle quota for orphan inodes87c1806601f2fs: support passing down write hints to block layer with F2FS policybcdc571e8df2fs: support passing down write hints given by users to block layer92413bc12ef2fs: fix to clear CP_TRIMMED_FLAGa1afb55f97f2fs: support large nat bitmap6360391404f2fs: fix to check extent cache in f2fs_drop_extent_tree7de4fccdbcf2fs: restrict inline_xattr_size configurationaae506a8b7f2fs: fix heap mode to reset it back8fa455bb6ef2fs: fix potential corruption in area before F2FS_SUPER_OFFSET9d9cb0ef73fscrypt: fix build with pre-4.6 gcc versions401052ffc6fscrypt: remove 'ci' parameter from fscrypt_put_encryption_info()549b2061b3fscrypt: fix up fscrypt_fname_encrypted_size() for internal usec440b5091afscrypt: define fscrypt_fname_alloc_buffer() to be for presented names7d82f0e1c3ext4: switch to fscrypt ->symlink() helper functionsba4efe5604ext4: switch to fscrypt_get_symlink()b0edc2f22dfscrypt: calculate NUL-padding length in one place only62cfdd9868fscrypt: move fscrypt_symlink_data to fscrypt_private.he4e6776522fscrypt: remove fscrypt_fname_usr_to_disk()45028b5aaaf2fs: switch to fscrypt_get_symlink()f62d3d31e0f2fs: switch to fscrypt ->symlink() helper functionsda32a1633afscrypt: new helper function -
