Subject: Missing put_cpu() in arch/s390/oprofile/hwsampler.c?
Date: Mon, 08 Aug 2011 19:51:53 +0200 [thread overview]
Message-ID: <1312825916.5589.150.camel@localhost.localdomain> (raw)
The function hws_oom_callback() seems to miss a corresponding put_cpu().
Or is this done in another function? I didn't find it.
