Subject: [PATCH] staging/lustre: annotate lock/unlock in lov_stripe_lock / lov_stripe_unlock
Date: Sat, 6 Sep 2014 12:20:06 +0200 [thread overview]
Message-ID: <1409998806-6413-1-git-send-email-mbmcode@gmail.com> (raw)
Annotate the lock/unlock pair in lov_stripe_lock/lov_stripe_unlock to
avoid sparse warning about a context imbalance.
