From: Steven Rostedt Date: Fri, 4 Nov 2011 20:32:25 +0000 (-0400) Subject: perf: Fix parsing of __print_flags() in TP_printk() X-Git-Tag: v3.2.1~32 X-Git-Url: https://git.openpandora.org/cgi-bin/gitweb.cgi?p=pandora-kernel.git;a=commitdiff_plain;h=923415295307845e614589c1cce62abedd4d1731 perf: Fix parsing of __print_flags() in TP_printk() 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.
