[Gluster-devel] tests/bugs/distribute/bug-1122443.t - spurious failure

[Nithya Balachandran]

Using git bisect, the patch that introduced this behaviour is :

commit 7131de81f72dda0ef685ed60d0887c6e14289b8c
Author: Krutika Dhananjay <kdhananj at redhat.com>
Date:   Tue Jan 17 16:40:04 2017 +0530

    performance/readdir-ahead: Invalidate cached dentries if they're
modified while in cache

Krutika, can you take a look and fix this?

To summarize, this is _not_ a spurious failure.


regards,
Nithya
