  sched_ext: idle: Handle migration-disabled tasks in BPF code (2025-09-22 06:24:44 -1000)

sched_ext: Fixes for v6.17-rc7

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.
