Commit fccaa81de87e ("f2fs: prevent atomic file from being dirtied before
commit")
adds the processing of FI_ATOMIC_DIRTIED in the following two positions,
[1]
f2fs_commit_atomic_write
- __f2fs_commit_atomic_write
- sbi->committed_atomic_block += fi->atomic_write_cnt;
- set_inode_flag(inode, FI_ATOMIC_COMMITTED);
- if (is_inode_flag_set(inode, FI_ATOMIC_DIRTIED)) {
- clear_inode_flag(inode, FI_ATOMIC_DIRTIED);
- f2fs_mark_inode_dirty_sync(inode, true);
- }
[2]
f2fs_abort_atomic_write
- if (is_inode_flag_set(inode, FI_ATOMIC_DIRTIED)) {
- clear_inode_flag(inode, FI_ATOMIC_DIRTIED);
- f2fs_mark_inode_dirty_sync(inode, true);
- }
but [1] seems to be redundant:
The atomic file flag FI_ATOMIC_FILE is still set here, so
f2fs_mark_inode_dirty_sync
still does not set the dirty state to vfs. If FI_ATOMIC_DIRTIED was originally
set
when atomic file is committing, then FI_ATOMIC_DIRTIED is just cleared here, and
then do the repeating action of setting FI_ATOMIC_DIRTIED?
So is it enough to do this only in [2]?
