Subject: [PATCH v2 0/2] powerpc/paravirt: vcpu_is_preempted() tweaks
Date: Tue, 28 Sep 2021 16:41:45 -0500 [thread overview]
Message-ID: <20210928214147.312412-1-nathanl@linux.ibm.com> (raw)
Minor changes arising from discovering that this code throws warnings with
DEBUG_PREEMPT kernels.
Changes since v1:
* Additional commentary to (1) distinguish hypervisor dispatch and preempt
behavior from kernel scheduler preemption; and (2) more clearly justify
the use of raw_smp_processor_id().
* Additional patch to update existing comments before making the functional
change.
v1: https://lore.kernel.org/linuxppc-dev/20210921031213.2029824-1-nathanl@linux.ibm.com/
