Subject: [PATCH RT 04/15] posixtimer: init timer only with CONFIG_POSIX_TIMERS enabled
Date: Fri, 01 Dec 2017 10:50:03 -0500	[thread overview]
Message-ID: <20171201155028.664412746@goodmis.org> (raw)
In-Reply-To: 20171201154959.375846909@goodmis.org

[-- Attachment #1: 0004-posixtimer-init-timer-only-with-CONFIG_POSIX_TIMERS-.patch --]
[-- Type: text/plain, Size: 944 bytes --]

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

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

From: Sebastian Andrzej Siewior <bigeasy@linutronix.de>

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.
