Subject: [PATCH v2 0/8] Replace PREEMPT_RT ifdefs with preempt_[dis|en]able_nested().
Date: Thu, 25 Aug 2022 18:41:23 +0200 [thread overview]
Message-ID: <20220825164131.402717-1-bigeasy@linutronix.de> (raw)
Folks,
this is v2 of "Replace PREEMPT_RT ifdefs with preempt_[dis|en]able_nested()."
The v1 is at
https://lore.kernel.org/all/20220817162703.728679-1-bigeasy@linutronix.de/
v1…v2:
- The SLUB patch got s/use_lockless_fast_path/USE_LOCKLESS_FAST_PATH/ as
Linus asked for and was handed over to Vlastimil and is sitting in his
slab tree:
https://git.kernel.org/vbabka/slab/c/591570a7
- The compaction patch got an "depends on COMPACTION" so it is not listed
.config if compaction is disabled (Rasmus Villemoes).
- The removal of u64_stats_fetch_begin_irq() has been excluded from the
series and staged for later. Jakub asked for this, so that it can be
included in later merge window.
- A patch for flex_proportions has been added which also needs a
preempt_disable_nested() since the merge window.
Original cover letter:
this is the follow up to the "vfs.git pile 3 - dcache" pull request [0].
It was concluded that the introduction of
preempt_disable_nested()
in general makes sense and should be used in places where preemption on
!RT is disabled by other means and PREEMPT_RT need to explicitly disable
it.
This series introduces the macro and converts already existing users to
that macro. The u64_stat interface was simplified to make the change
simpler and code easier to follow.
