Subject: [PATCH 3/3] [PATCH 3/3] oprofile: fix oprofile regression: select RING_BUFFER_ALLOW_SWAP
Date: Thu, 17 Sep 2009 00:27:34 -0400 [thread overview]
Message-ID: <20090917042831.921998149@goodmis.org> (raw)
In-Reply-To: 20090917042731.630008734@goodmis.org
[-- Attachment #1: 0003-oprofile-fix-oprofile-regression-select-RING_BUFFER_.patch --]
[-- Type: text/plain, Size: 1048 bytes --]
From: Christian Borntraeger <borntraeger@de.ibm.com>
commit 85bac32c4a52c592b857f2c360cc5ec93a097d70
ring-buffer: only enable ring_buffer_swap_cpu when needed
broke oprofile (at least on s390, but likely on all platforms).
this patch lets oprofile select RING_BUFER_ALLOW_SWAP to make
ring_buffer_swap_cpu usable for oprofile.
