[PATCH RT 04/15] posixtimer: init timer only with CONFIG_POSIX_TIMERS enabled

From: Steven Rostedt
Date: Fri Dec 01 2017 - 10:51:49 EST


4.9.65-rt57-rc1 stable review patch.
If anyone has any objections, please let me know.

------------------

From: Sebastian Andrzej Siewior <bigeasy@xxxxxxxxxxxxx>

In v4.11 it is possible to disable the posix timers and so we must not
attempt to initialize the task_struct on RT with !POSIX_TIMERS.
This patch does so.
