Date: Tue, 22 Aug 2006 11:52:25 -0700 From: Josh Triplett <josht@...ibm.com> To: linux-kernel@...r.kernel.org Cc: Andrew Morton <akpm@...l.org>, Paul McKenney <paulmck@...ibm.com>, Dipkanar Sarma <dipankar@...ibm.com> Subject: [PATCH] SRCU: add lock annotations to srcu_read_lock and srcu_read_unlock Add an __acquires annotation to srcu_read_lock, and add a __releases annotation to srcu_read_unlock. This allows static analysis tools to detect improperly paired calls to these functions.
