--- Comment #4 from Raghavendra G <rgowdapp at redhat.com> ---
Except for how mkdir by non-root user succeeded in my test above, other things
can be answered.

* gfid is never set as a separate setxattr call sent through posix-acl. All
posix-acl sees is a create/mkdir/symlink/mknod operation.
* xattrop is not implemented by posix-acl (rightly so, as it is an internal
operation). So, doesn't affect afr changelog etc.
* however it will affect any metadata setting done through setxattr (dht
layouts, marker dirty flags etc).

Based on Nithya's analysis, I agree this patch is needed and solves the issue
present here (though there are some open questions which are not directly
related to this bz).
