Subject: LU-5982 lfsck: not unlock the object repeatedly
X-Git-Tag: 2.6.92~85
X-Git-Url: https://git.whamcloud.com/?p=fs%2Flustre-release.git;a=commitdiff_plain;h=8ee9c59a3688e5026ebb914190b63970135ce2e5

LU-5982 lfsck: not unlock the object repeatedly

There was wrong logic in lfsck_namespace_insert_orphan() that tried to
unlock the same object twice if failed to update the object's linkEA,
then triggered low layer LBUG(). Fix it.

On the other hand, the remote orphan parent object should be marked as
LOHA_EXISTS after lfsck_namespace_create_orphan_remote() done.

Some test scripts cleanup.
