Subject: [PATCH v4 0/8] lockdep: Change IRQ state tracking to use per-cpu variables
Date: Tue, 23 Jun 2020 10:36:45 +0200 [thread overview]
Message-ID: <20200623083645.277342609@infradead.org> (raw)
Ahmed and Sebastian wanted additional lockdep_assert*() macros and ran into
header hell. I figured using per-cpu variables would cure that, and also
ran into header hell, still tracktable though.
By moving the IRQ state into per-cpu variables we remove the dependency on
task_struct.
Patches go on top of anything recent I think, an actual git tree with them
in is (for now) here:
git://git.kernel.org/pub/scm/linux/kernel/git/peterz/queue.git locking/irqstate
Which 0day blessed with 0 build fails.
