| |
3.0-stable review patch. If anyone has any objections, please let me know.
------------------
From: Steven Rostedt <srostedt@redhat.com>
commit 49908a1b25d448d68fd26faca260e1850201575f upstream.
A update is made to the sched:sched_switch event that adds some logic to the first parameter of the __print_flags() that shows the state of tasks. This change cause perf to fail parsing the flags.
A simple fix is needed to have the parser be able to process ops within the argument.
