Subject: [GIT PULL] SMP cross-call changes for v6.4
Date: Thu, 27 Apr 2023 23:09:08 +0200 [thread overview]
Message-ID: <ZErkdNBn7OLkQZWC@gmail.com> (raw)
Linus,
Please pull the latest smp/core git tree from:
git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git smp-core-2023-04-27
# HEAD: 5c3124975e15c1fadd5af1c61e4d627cf6d97ba2 trace,smp: Trace all smp_function_call*() invocations
SMP cross-CPU function-call updates for v6.4:
- Remove diagnostics and adjust config for CSD lock diagnostics
- Add a generic IPI-sending tracepoint, as currently there's no easy
way to instrument IPI origins: it's arch dependent and for some
major architectures it's not even consistently available.
Thanks,
Ingo
------------------>
