Can you explain what exactly you're trying to do there? I've been
trying to unwrap what's going on and can't really see the point:
- i_acl_mode and FI_ACL_MODE get set in __setattr_copy, but right
after that call, still under i_mutex and before marking the inode
dirty f2fs_acl_chmod makes use of it, and it gets cleared right
after. Is there any race that could happen with a locked inode
not marked dirty yet on f2fs? We could pass a mode argument
to posix_acl_create, but I'd prefer to avoid that if we can.
- on the set_acl side it gets set in __f2fs_set_acl, and then
i_mode is update in __f2fs_setxattr which could easily done with
a stack variable.

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.
