--- Comment #2 from Worker Ant <bugzilla-bot at gluster.org> ---
COMMIT: https://review.gluster.org/20120 committed in master by "Amar Tumballi"
<amarts at redhat.com> with a commit message- posix/ctime: Fix fops racing in
updating mtime/atime

In distributed systems, there could be races with fops
updating mtime/atime which could result in different
mtime/atime for same file. So updating them only if
time is greater than the existing makes sure, only
the highest time is retained. If the mtime/atime
update comes from the explicit utime syscall, it is
allowed to set to previous time.

Thanks Xavi for helping in rooting the issue.
