[PATCH 6.7 273/309] tools/rtla: Replace setting prio with nice for SCHED_OTHER

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



6.7-stable review patch.  If anyone has any objections, please let me know.

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

From: limingming3 <limingming890315@xxxxxxxxx>

commit 14f08c976ffe0d2117c6199c32663df1cbc45c65 upstream.

Since the sched_priority for SCHED_OTHER is always 0, it makes no
sence to set it.
Setting nice for SCHED_OTHER seems more meaningful.
