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.

RFC patch below:

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.

Thanks,
