tools lib traceevent kbuffer: Remove extra update to data pointer in PADDING

2015-05-06T20:01:54+00:00

commit c5e691928bf166ac03430e957038b60adba3cf6c upstream.

When a event PADDING is hit (a deleted event that is still in the ring
buffer), translate_data() sets the length of the padding and also updates
the data pointer which is passed back to the caller.

This is unneeded because the caller also updates the data pointer with
the passed back length. translate_data() should not update the pointer,
only set the length.

tools/liblockdep: don't include host headers

2015-01-30T02:55:19+00:00

Adding host headers to include path may cause unexpected surprises when cross
compiling. Remove /usr/local/include from the default include path.

perf tools: Fix statfs.f_type data type mismatch build error with uclibc

2015-01-16T20:49:29+00:00

ARC Linux uses the no legacy syscalls abi and corresponding uClibc headers
statfs defines f_type to be U32 which causes perf build breakage

Merge branch 'liblockdep-fixes-3.19' of git://git.kernel.org/pub/scm/linux/kernel/git/sashal/linux into core/urgent

2014-12-23T09:27:44+00:00

Pull a liblockdep fix from Sasha Levin:

 "A small (but important) fix to the way we detect freeing live locks. We would
  pass a wrong memory region when testing for locks inside freed memory spaces,
  which would trigger false positives."

tools/liblockdep: Fix debug_check thinko in mutex destroy

2014-12-19T20:50:55+00:00

In mutex destroy code currently we pass to debug_check_no_locks_freed()

    [mem_from, mem_end)

address region. But debug_check_no_locks_freed() accepts

    mem_from, mem_*len*

i.e. second parameter is region length, not end address. And it was
always so, starting from 2006 (fbb9ce95 "lockdep: core").

Fix it, or else on a mutex destroy we wrongly check
much-wider-than-mutex region and can find not-yet-released other locks
there and wrongly report BUGs on them.
