[PATCH 4/8] drbd: Avoid inconsistent locking warning

From: Philipp Reisner
Date: Mon Aug 25 2014 - 09:26:08 EST


From: Andreas Gruenbacher <agruen@xxxxxxxxxx>

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.
