Is there any race that could happen with a locked inode > not marked dirty yet on f2fs? As you guess, there is no race problem, but the problem is on acl consistency between xattr->mode and inode->mode. Previously, f2fs_setattr triggers: new_mode inode->mode xattr->mode iblock->mode f2fs_setattr x -> x y y [update_inode] x --- [ y ] ---> x [checkpoint] x y x __f2fs_setxattr x -> x x In this flow, f2fs is able to break the consistency between xattr->mode and iblock->mode after checkpoint followed by sudden-power-off. So, fi->mode was introduced to address the problem. The new f2fs_setattr triggers: new_mode inode->mode fi->mode xattr->mode iblock->mode f2fs_setattr x --- [y] ---> x y y [update_inode] y x y y [checkpoint] y x y y __f2fs_setxattr x <- x -> x -> x Finally, __f2fs_setxattr synchronizes inode->mode, xattr->mode, and iblock->mode all together. The root question is "is it possible to call update_inode in the i_mutex-covered region like f2fs_setattr?". The update_inode of f2fs is called from a bunch of places so currently I'm not sure it can be impossible.
