From 38b5ff4d07146ad2359018c3f4707125d38c421f Mon Sep 17 00:00:00 2001 From: Etienne Dechamps Date: Mon, 16 Jul 2012 16:33:40 +0200 Subject: Fix undefined reference on spl_mutex_spin_max(). Commit 3160d4f56bf35492e9c400094f8c1ff2066d4459 changed the set of conditions under which spl_mutex_spin_max would be implemented as a function by changing an #if in sys/mutex.h. The corresponding implementation file spl-mutex.c, however, has not been updated to reflect the change. This results in undefined reference errors on spl_mutex_spin_max under the following condition: ((!CONFIG_SMP || CONFIG_DEBUG_MUTEXES) && HAVE_MUTEX_OWNER && HAVE_TASK_CURR) This patch fixes the issue by using the same #if in sys/mutex.h and spl-mutex.c.
