posix-cpu-timers: cpu_clock_sample_group() no longer needs siglock
As of e78c3496790e ("time, signal: Protect resource use statistics with seqlock") cpu_clock_sample_group() no longer needs siglock protection so remove the stale comment. Signed-off-by: "Eric W. Biederman" <ebiederm@xmission.com> Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Link: https://lkml.kernel.org/r/87eeuevduq.fsf@x220.int.ebiederm.org
