Subject: sched/deadline: Don't check SD_BALANCE_FORK
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=1d7e974cbf2fce2683f34ff33c173fd7ef5478c7;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

sched/deadline: Don't check SD_BALANCE_FORK

There is no need to do balance during fork since SCHED_DEADLINE
tasks can't fork. This patch avoid the SD_BALANCE_FORK check.
