Subject: __hw_perf_counter_init() on x86
Date: Tue, 08 Sep 2009 23:49:18 -0700 (PDT) [thread overview]
Message-ID: <20090908.234918.174793485.davem@davemloft.net> (raw)
It seems that for most of the error returns this function
can give, we'll leak the active_counters count grabbed
at the beginning of the function and therefore we'll never
re-enable the LAPIC NMI watchdog even once all the perf
counter users go away.
Just FYI...
