Subject: [PATCH 0/4] sched/fair: Rework tash_h_load()
Date: Fri, 28 Aug 2026 09:40:59 +0200	[thread overview]
Message-ID: <20260828074059.232353141@infradead.org> (raw)

Hi!

So task_h_load() has been known buggered for a while [1], and while looking at
[2] I ran into it again.

These few patches rework the thing and should hopefully result in less broken
behaviour.

Lightly tested...
