[PATCH 0/3] perf: Disable user space dumps for function trace event

[Jiri Olsa <jolsa@redhat.com>]

hi,
recent issues with user space callchains processing within
page fault handler tracing showed as Peter said 'there's
just too much fail surface'.

Disabling user space callchain and stack dump for
function trace event. Plus updating the perf tool
to keep up with those changes.

Reachable here:

thanks,
jirka
