[PATCH 0/3] perf tools: Factor perf data handling

[Jiri Olsa <jolsa@redhat.com>]

hi,
adding patches to centralize perf.data handling. New object
perf_data_file is added as a handler for perf.data file.

This cleans up perf.data handling and will become handy
for other perf.data file related changes in future, like
multiple file storage or separating storage into multiple
threads.

This patchset is extracted and rebased as generic one
from my earlier 'multiple file support' patchset:
http://marc.info/?t=137803189400001&r=1&w=2

It's reachable here:
git://git.kernel.org/pub/scm/linux/kernel/git/jolsa/perf.git
perf/file38

thanks,
jirka
