Subject: [PATCH] staging: lustre: Fix 'unexpected unlock' warning generated by sparse
Date: Sun, 3 Jan 2016 08:27:04 +0530	[thread overview]
Message-ID: <20160103025704.GA31228@codebox> (raw)

Added annotation '__must_hold' to function ksocknal_send_keepalive_locked
which unlocks the lock ksocknal_data.ksnd_global_lock. As this lock is
not acquired in the current function, sparse warns about context imbalance
