Subject: [PATCH v3 00/20] seqlock: Extend seqcount API with associated locks
Date: Tue, 30 Jun 2020 07:44:32 +0200 [thread overview]
Message-ID: <20200630054452.3675847-1-a.darwish@linutronix.de> (raw)
In-Reply-To: <20200519214547.352050-1-a.darwish@linutronix.de>
Hi,
This is v3 of the seqlock patch series:
[PATCH v1 00/25] seqlock: Extend seqcount API with associated locks
https://lore.kernel.org/lkml/20200519214547.352050-1-a.darwish@linutronix.de
[PATCH v2 00/18]
https://lore.kernel.org/lkml/20200608005729.1874024-1-a.darwish@linutronix.de
It's based over:
git://git.kernel.org/pub/scm/linux/kernel/git/peterz/queue.git locking/core
to get Peter's lockdep irqstate tracking series below, which untangles
mainline seqlock.h<=>sched.h 'current->' task_struct circular dependency:
https://lkml.kernel.org/r/linuxppc-dev/20200623083645.277342609@infradead.org
Changelog-v3:
- Re-add lockdep non-preemptibility checks on seqcount_t write paths.
They were removed from v2 due to the circular dependencies mentioned.
- Slight rebase over the new v5.8-rc1 KCSAN seqlock.h changes
- Collect seqcount_t call-sites acked-by tags
Thanks,
8<--------------
