Subject: [PATCHSET 0/9] perf tools: Fix for compressed kernel modules (v4)

Hello,

This is v4 of my compressed kernel module work.  Please take a look.

 * changes in v4)
  - fix build-id cache symbolic link handling in annotate
  - separate fix for a memory leak  (Arnaldo)
  - consolidate error path in __open_dso  (Arnaldo)
  - remove decompressed file after use

The code is avaiable at 'perf/kmod-decomp-v4' branch in my tree:

  git://git.kernel.org/pub/scm/linux/kernel/git/namhyung/linux-perf.git

Thanks,
Namhyung
