Subject: [PATCH 0/2] [GIT PULL] tracing: A couple of fixes to tracepoints

Linus,

This contains two fixes.

The first is a long standing bug that causes bogus data to show up
in the refcnt field of the module_refcnt tracepoint. It was
introduced by a merge conflict resolution back in 2.6.35-rc days.

The result should be refcnt = incs - decs, but instead it did
refcnt = incs + decs.

The second fix is to a bug that was introduced in this merge window
that allowed for a tracepoint funcs pointer to be used after it
was freed. Moving the location of where the probes are released
solved the problem.
