From bdb43806589096ac4272fe1307e789846ac08d7c Mon Sep 17 00:00:00 2001 From: Peter Zijlstra Date: Tue, 10 Sep 2013 12:15:23 +0200 Subject: sched: Extract the basic add/sub preempt_count modifiers Rewrite the preempt_count macros in order to extract the 3 basic preempt_count value modifiers: __preempt_count_add() __preempt_count_sub() and the new: __preempt_count_dec_and_test() And since we're at it anyway, replace the unconventional $op_preempt_count names with the more conventional preempt_count_$op. Since these basic operators are equivalent to the previous _notrace() variants, do away with the _notrace() versions.
