[PATCH] trace-cmd: Make read nonblocking in find_time_stamp()
This only affects the tsc -> time of day correlation when doing
`trace-cmd record --date`.
get_date_to_ts() writes a dummy event to trace_marker and then reads it back.
Reading it back is done by looping over all per-cpu raw trace pipes and trying
to read. This read should be non-blocking, because the dummy event can end up
on any CPU.
Switching to rhel6.8 as this is not urgent
The fix for this is in trace-cmd-v2.2.4 so was fixed in bz1218670
Available in 2.2.4-1 and up
