Subject: [PATCH v4 00/24] seqlock: Extend seqcount API with associated locks
Date: Mon, 20 Jul 2020 17:55:06 +0200 [thread overview]
Message-ID: <20200720155530.1173732-1-a.darwish@linutronix.de> (raw)
In-Reply-To: <20200519214547.352050-1-a.darwish@linutronix.de>
Hi,
This is v4 of the seqlock patch series:
[PATCH v1 00/25]
https://lore.kernel.org/lkml/20200519214547.352050-1-a.darwish@linutronix.de
[PATCH v2 00/06] (bugfixes-only, merged)
https://lore.kernel.org/lkml/20200603144949.1122421-1-a.darwish@linutronix.de
[PATCH v2 00/18]
https://lore.kernel.org/lkml/20200608005729.1874024-1-a.darwish@linutronix.de
[PATCH v3 00/20]
https://lore.kernel.org/lkml/20200630054452.3675847-1-a.darwish@linutronix.de
It is based over:
git://git.kernel.org/pub/scm/linux/kernel/git/peterz/queue.git :: locking/core
Changelog
=========
- Unconditionally use C11 _Generic() expressions for seqcount_locktype_t
switching. Thanks to Peter, pushing for 6ec4476ac825 ("Raise gcc
version requirement to 4.9").
- Compress the new seqcount_locktype_t code code by using generative
macros, as suggested by Peter here:
https://lkml.kernel.org/r/20200708122938.GQ4800@hirez.programming.kicks-ass.net
Keep *all* functions that are to be invoked by call-sites out of such
generative macros though. This simplifies the generative macros code,
and (more importantly) make the newly exported seqlock.h API explicit.
- Make all documentation "RST-lite", for better readability from text
editors.
- Add additional clean-ups at the start of the series for better
overall readability of seqlock.h code, and for future extensibility.
Thanks,
8<--------------
