Subject: [PATCH 0/4] s390: Remove or replace cond_resched() calls
Date: Mon, 27 Jul 2026 18:24:26 +0200 [thread overview]
Message-ID: <20260727162430.1599396-1-hca@linux.ibm.com> (raw)
Since [1] it is only possible to select the PREEMPT or PREEMPT_LAZY
preemption models for s390. This has caused some minor problems, but
everything has been addressed.
Given that for both preemption models cond_resched() is a no-op remove
or replace it everywhere.
[1] commit 7dadeaa6e851 ("sched: Further restrict the preemption modes")
Heiko Carstens (4):
s390/crypto: Replace cond_resched() with schedule()
KVM: s390: Remove cond_resched() calls
s390: Remove cond_resched() calls
s390/cio: Remove cond_resched() calls
