Subject: [PATCH] perf_counter: do not create perf counter mlock sysctl when CONFIG_PERF_COUNTERS=n
Date: Fri, 22 May 2009 10:42:53 +0100 [thread overview]
Message-ID: <1242985373.22654.225.camel@zakaz.uk.xensource.com> (raw)
Building tip from 82811bee3 without CONFIG_PERF_COUNTERS results in:
CC kernel/sysctl.o
kernel/sysctl.c:928: error: 'sysctl_perf_counter_mlock' undeclared here (not in a function)
This is due to c5078f78b "perf_counter: provide an mlock threshold"
