Subject: [PATCH 0/2] tracing,mm - add kernel pagefault tracepoint for x86 & x86_64
Date: Wed, 10 Nov 2010 12:56:10 +0100	[thread overview]
Message-ID: <1289390172-9730-1-git-send-email-jolsa@redhat.com> (raw)

This provides a tracepoint to trace kernel pagefault event
for x86 and x86_64 architectures.

There's a problem with this tracepoint when having the
userstacktrace option enabled, since it might generated
the page fault itself. The 2/2 patch address this issue.

attached patches:
1/2 tracing,mm - add kernel pagefault tracepoint for x86 & x86_64
2/2 tracing - fix recursive user stack trace

wbr,
jirka
