    Subject[13/40] perf: Fix parsing of __print_flags() in TP_printk()
    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.
