Pull f2fs updates from Jaegeuk Kim: "In this round, we've refactored the existing atomic write support implemented by in-memory operations to have storing data in disk temporarily, which can give us a benefit to accept more atomic writes. At the same time, we removed the existing volatile write support. We've also revisited the file pinning and GC flows and found some corner cases which contributeed abnormal system behaviours. As usual, there're several minor code refactoring for readability, sanity check, and clean ups. Enhancements: - allow compression for mmap files in compress_mode=user - kill volatile write support - change the current atomic write way - give priority to select unpinned section for foreground GC - introduce data read/write showing path info - remove unnecessary f2fs_lock_op in f2fs_new_inode Bug fixes: - fix the file pinning flow during checkpoint=disable and GCs - fix foreground and background GCs to select the right victims and get free sections on time - fix GC flags on defragmenting pages - avoid an infinite loop to flush node pages - fix fallocate to use file_modified to update permissions consistently" * tag 'f2fs-for-5.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs: (40 commits) f2fs: fix to tag gcing flag on page during file defragment f2fs: replace F2FS_I(inode) and sbi by the local variable f2fs: add f2fs_init_write_merge_io function f2fs: avoid unneeded error handling for revoke_entry_slab allocation f2fs: allow compression for mmap files in compress_mode=user f2fs: fix typo in comment f2fs: make f2fs_read_inline_data() more readable f2fs: fix to do sanity check for inline inode f2fs: fix fallocate to use file_modified to update permissions consistently f2fs: don't use casefolded comparison for "." and ".." f2fs: do not stop GC when requiring a free section f2fs: keep wait_ms if EAGAIN happens f2fs: introduce f2fs_gc_control to consolidate f2fs_gc parameters f2fs: reject test_dummy_encryption when !CONFIG_FS_ENCRYPTION f2fs: kill volatile write support f2fs: change the current atomic write way f2fs: don't need inode lock for system hidden quota f2fs: stop allocating pinned sections if EAGAIN happens f2fs: skip GC if possible when checkpoint disabling f2fs: give priority to select unpinned section for foreground GC ...

f2fs: replace F2FS_I(inode) and sbi by the local variable

2022-05-27T20:58:23Z

We have define 'fi' at the begin of the functions, just use it, rather than use F2FS_I(inode) again. Signed-off-by: Yufen Yu Reviewed-by: Chao Yu [Jaegeuk Kim: replace sbi] Signed-off-by: Jaegeuk Kim

f2fs: add f2fs_init_write_merge_io function

2022-05-25T17:48:56Z

Almost all other initialization of variables in f2fs_fill_super are extraced to a single function. Also do it for write_io[], which can make code more clean. This patch just refactors the code, theres no functional change. Signed-off-by: Yufen Yu Reviewed-by: Chao Yu [Jaegeuk Kim: clean up] Signed-off-by: Jaegeuk Kim

f2fs: avoid unneeded error handling for revoke_entry_slab allocation

f2fs: allow compression for mmap files in compress_mode=user

2022-05-25T06:06:38Z

Since commit e3c548323d32 ("f2fs: let's allow compression for mmap files"), it has been allowed to compress mmap files. However, in compress_mode=user, it is not allowed yet. To keep the same concept in both compress_modes, f2fs_ioc_(de)compress_file() should also allow it. Let's remove checking mmap files in f2fs_ioc_(de)compress_file() so that the compression for mmap files is also allowed in compress_mode=user.
