Subject[18/49] perf: Fix parsing of __print_flags() in TP_printk()
3.2-stable review patch.  If anyone has any objections, please let me know.

From: Steven Rostedt <>

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.
