| |
Just a tiny cleanup I did while I was looking through scheduler code doing a tasklist_lock change. Please consider applying if you find it appropriate.
------------------------------8<----------------------------------------- sched: make sched_group_{get,set}_rt_{runtime,period} functions static
These functions, as well as sched_rt_can_attach(), used to be public so that kernel/user.c could use them; however this use has now disappeared so that these functions can be made static again.
