Subject: perf test: Skip sched stats test for !root
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=dc647eb00969cd213c84d6caee90c480317e857d;p=thirdparty%2Fkernel%2Flinux.git

perf test: Skip sched stats test for !root

Running perf sched stats requires root and it fails to open the
schedstat file for regular users.  Let's skip the test.

  $ perf sched stats true
  Failed to open /proc/sys/kernel/sched_schedstats
