Sunny/Rafi,
I was trying to debug regression failures on [1]. Note that patch [1] only disables usage of anonymous fds on readv. So, I tried the same test disabling performance.open-behind[root@rhs-client27 glusterfs]# git diff
diff --git a/tests/bugs/snapshot/bug-1167580-set-proper-uid-and-gid-during-nfs-access.t b/tests/bugs/snapshot/bug-1167580-set-proper-uid-and-gid-during-nfs-access.t

With the above change, I can see consistent failures of the test just like observed in [1].

I had a feeling this test fails spuriously and the spurious nature is tied with whether open-behind uses an anonymous fd or a regular fd for read.
@Sunny,
This test is blocking two of my patches - [1] and [2]. Can I mark this test as bad and proceed with my work on [1] and [2]?

Raghavendra
