Description

The error happens during soak testing of build '20151214' (see https://wiki.hpdd.intel.com/display/Releases/Soak+Testing+on+Lola#SoakTestingonLola-20151214)

During normal soak operations (no fault injected) approximately 5% of the test (batch) jobs crash.
The events can be correlated to the error message

can be reproduced with ZFS and ldiskfs

I'm hitting this locally (very rare).. it seems the root cause is that failed mkdir can't cleanup the name sometimes, then subsequent lookup/stat/whatever finds that in broken state (the name and one stripe exist, but another stripe doesn't).
