Merge tag 'trace-fixes-v3.10-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace
Pull tracing fix from Steven Rostedt:
"Yoshihiro Yunomae fixed a regression in the output format when using
one of the counter clocks.
The new multibuffer code changed the trace_clock file to update the
trace instances tr->clock_id but the actual traces still used the
value from the obsolete global variable trace_clock_id"
* tag 'trace-fixes-v3.10-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace:
tracing: Fix outputting formats of x86-tsc and counter when use trace_clock
