Subject: [PATCH -v2 0/5] sched: TTWU, IPI and stuff
Date: Mon, 22 Jun 2020 12:01:22 +0200 [thread overview]
Message-ID: <20200622100122.477087977@infradead.org> (raw)
Hi,
Like earlier, Paul's rcutorture is fixed by #1, but now it actually makes sense
and I can explain how it happens. Therefore this patch is _much_ better than the
last one :-)
I was going to push 1-3 into sched/urgent, #3 removes the horrible BUG_ON crap in
kernel/smp.c and trades them for slightly less horrible unions.
I was planning on keeping #4,#5 back for the next round, but if Linus wants
them now, that can certainly be arranged too. I have some further work on top
that creates and uses irq_work_queue_remote() to replace many (hopefully all)
smp_call_function_single_async() users so we can get rid of that head-ache, but
those need to cook a little more.
(#5 has 'trivial' conflicts with patches from hch that are targeted at
the next round)
