Re: [PATCH] sched_ext: Fix use-after-free of a destroyed user DSQ by a deferred reenqueue

[Hui Su]

Hi Tejun,

Tested on x86_64 KVM with KASAN; sched_ext selftests passed, and the targeted
DSQ lifetime test completed without the pre-fix slab-use-after-free.

Tested-by: Hui Su <sh_def@xxxxxxx>

Thanks,
Hui
