From a238b790d5f99c7832f9b73ac8847025815b85f7 Mon Sep 17 00:00:00 2001 From: Jonathan Corbet Date: Fri, 20 Jun 2008 09:12:01 -0600 Subject: Call fasync() functions without the BKL lock_kernel() calls have been pushed down into code which needs it, so there is no need to take the BKL at this level anymore. This work inspired and aided by Andi Kleen's unlocked_fasync() patches.
