Subject: [PATCH 4/9] drbd: Avoid inconsistent locking warning
Date: Thu, 11 Sep 2014 14:29:08 +0200 [thread overview]
Message-ID: <1410438553-30440-5-git-send-email-philipp.reisner@linbit.com> (raw)
In-Reply-To: <1410438553-30440-1-git-send-email-philipp.reisner@linbit.com>
From: Andreas Gruenbacher <agruen@linbit.com>
request_timer_fn() takes resource->req_lock via the device and releases it via
the connection. Avoid this as it is confusing static code checkers.
