Subject: [PATCH 0/6] x86/entry,lockdep: Improve IRQ state tracking
Date: Wed, 27 May 2020 17:45:27 +0200 [thread overview]
Message-ID: <20200527154527.233385756@infradead.org> (raw)
Ahmed and Sebastian wanted additional lockdep_assert*() macros and ran
into header hell.
Move the IRQ state into per-cpu variables, which removes the dependency on
task_struct, which is what generated the header-hell.
And fix IRQ state tracking to not be affected by lockdep_off() (it really
should not have been anyway) and extends IRQ state tracking across (x86)
NMIs.
