[PATCH 0/5] perf record: Allow to ignore missing pid

[Jiri Olsa <jolsa@kernel.org>]

hi,
this patches allows record's -u option to ignore group of
pids, that 'disappear' before perf opens their event.

This currently leads perf to report error and exit.

With this change we will allow this race and ignore such
failure with warning:

  $ perf record -u
  WARNING: Ignored open failure for pid 8605
  ...

and continue monitoring whatever portion of processes
we managed to open.

Plus one extra perf mem fix.

thanks,
jirka
