From: Steven Rostedt Date: Tue, 27 Apr 2010 17:26:58 +0000 (-0400) Subject: ring-buffer: Make benchmark handle missed events X-Git-Tag: v2.6.35-rc1~520^2~9 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=a838b2e634405fb89ddbf4fa9412acb33911911f;p=pandora-kernel.git ring-buffer: Make benchmark handle missed events With the addition of the "missed events" flags that is stored in the commit field of the ring buffer page, the ring_buffer_benchmark was not updated to handle this. If events are missed, then the missed events flag is set in the ring buffer page, the benchmark will count that flag as part of the size of the page and will hit the BUG() when it tries to read beyond the page. The solution is simply to have the ring buffer benchmark mask off the extra bits. Reported-by: Ingo Molnar Signed-off-by: Steven Rostedt --- Reading git-diff-tree failed
