From 8db732668a48e93d00d881517a08136e8fa71000 Mon Sep 17 00:00:00 2001 From: Raghavendra K T Date: Fri, 9 Aug 2013 19:51:50 +0530 Subject: x86, ticketlock: Don't inline _spin_unlock when using paravirt spinlocks The code size expands somewhat, and its better to just call a function rather than inline it. Thanks Jeremy for original version of ARCH_NOINLINE_SPIN_UNLOCK config patch, which is simplified.
