Subject: [PATCH] perf_counter: call atomic64_set for counter->count
Date: Mon, 11 May 2009 15:50:21 +1000 [thread overview]
Message-ID: <18951.48285.270311.981806@drongo.ozlabs.ibm.com> (raw)
This fixes a compile warning where we are calling
atomic_set(&counter->count). Since counter->count is an atomic64_t,
we have to use atomic64_set.
[ Impact: fix type mismatch bug ]
