7c02f94255 ANDROID: Incremental fs: fix magic compatibility again
It's still magic number issue which cannot be compatible with
arm-32 platform, although we try to fix it in Iae4f3877444
("ANDROID: Incremental fs: magic number compatible 32-bit"),
there is still incompatible scenario, such as: get_incfs_node(),
it will return NULL then kernel exception will be trigger because
of NULL pointer access. (inode_set() -> get_incfs_node(), then used
node->xxx directly)

We change magic number directly, otherwise, we must fix above issues one by one.

ca72c79936 ANDROID: Incremental fs: Protect get_fill_block, and add a field
Since INCFS_IOC_GET_FILLED_BLOCKS potentially leaks information about usage
patterns, and is only useful to someone filling the file, best protect it in
the same way as INCFS_IOC_FILL_BLOCKS.

Add useful field data_block_out as well

21b07a7140 ANDROID: Incremental fs: Make fill block an ioctl
Filling blocks is not equivalent to writing a file, since they are
constrained by the root hash. selinux policy may wish to treat them
differently, for instance.
