| |
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.
Please pull the latest trace-fixes-v3.15-rc4-v2 tree, which can be found at:
