caused the issue was done by Nithya. Following was the conversation:

With the latest master, I created a single brick volume and some files
inside it.

Conversation can be followed on gluster-devel on thread with subj:
tests/bugs/distribute/bug-1122443.t - spurious failure. git-bisected
pointed this patch as culprit.
</snip>
commit 7131de81f72dda0ef685ed60d0887c6e14289b8c zeroed out all members of
iatt except for ia_gfid and ia_type in certain scenarios (one case that led
to this bug was when a fresh inode - not linked - was picked up by
readdirplus). This led to fuse_readdirp_cbk to wrongly think it has a valid
stat (due to valid ia_gfid and ia_type) and give to kernel zeroed out
attributes causing failures. Fix is included in
https://review.gluster.org/20639 to make sure to let kernel know attributes
are not valid in this scenario (and not zero out stats even if inode picked
up by readdirplus is not linked yet).
