Ingo Molnar 613d860229 perf record: Fix fast task-exit race ... Recording with -a (or with -p) can race with tasks going away: couldn't open /proc/8440/maps Causing an early exit() and no recording done. Do not abort the recording session - instead just skip that task. Also, only print the warnings under -v.
