[PATCH 28/60] staging: lustre: ldlm: ASSERTION(flock->blocking_export!=0) failed

From: James Simmons
Date: Sat Jan 28 2017 - 19:14:06 EST


From: Andriy Skulysh <andriy.skulysh@xxxxxxxxxxx>

Whole policy structure was zeroed twice. Once during enqueue
and second time during resend or replay. Policy structure
should be initialized with default values only in ldlm_lock_new().
