Merge tag 'sched_ext-for-6.17-rc7-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/sched_ext
Pull sched_ext fix from jun Heo:
"This contains a fix for sched_ext idle CPU selection that likely fixes
a substantial performance regression.
The scx_bpf_select_cpu_dfl/and() kfuncs were incorrectly detecting all
tasks as migration-disabled when called outside ops.select_cpu(),
causing them to always return -EBUSY instead of finding idle CPUs.
The fix properly distinguishes between genuinely migration-disabled
tasks vs. the current task whose migration is temporarily disabled by
BPF execution"
