Re: [PATCH] sched_ext: Specialize the DSQ hashtable compare

From: Tejun Heo

Applied to sched_ext/for-7.4 with the dsq_cmpfn() signature joined onto one
line.

scx_tid_hash and scx_sched_hash have the same u64 key and also fall back to
rhashtable_compare(). scx_bpf_tid_to_task() sits on hot paths too. Do you
want to do the same for them as a follow-up?

Thanks.
