Subject: [PATCH 0/5] perf session: Add reader object

hi,
this patchset adds reader object to interface event
processing for any data. It's defined as:

  struct reader {
        int fd;
        u64 data_size;
        u64 data_offset;
  };

Now we can simply define reader object for arbitrary file
data portion and pass it to reader__process_events function
to process its data.

It's preparation for multiple file storage under perf.data
directory.

Available also in:
  git://git.kernel.org/pub/scm/linux/kernel/git/jolsa/perf.git
  perf/fixes

thanks,
jirka
