Subject: Re: [PATCH v2] sched_ext: Skip per-CPU data allocation for built-in DSQs
Date: Tue, 01 Sep 2026 20:57:04 -1000 [thread overview]
Message-ID: <bbc31cd1b97a4d0d169103b391a278cb@kernel.org> (raw)
In-Reply-To: <20260901013258.1822890-1-fangqiurong@kylinos.cn>
Applied to sched_ext/for-7.4 with Zhan's Reviewed-by added, the description
reworded to say the waste is quadratic in the CPU count, and the
scx_init_dsq() comment reworded as the local DSQ does track deferred reenqs,
just through sch->pcpu.
Thanks.
