Subject: [PATCH 101/333] sched/fair: Make the hrtimers non-hard again
|
|
Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/4.19/older/patches-4.19.148-rt64.tar.xz
|
|
|
|
Since commit "sched/fair: Robustify CFS-bandwidth timer locking" both
|
|
hrtimer can run in softirq context because now interrupts are disabled
|
|
as part of the locking procedure.
