Subject: [PATCH 00/14] lockdep: Add lightweight IRQs disabled/enabled check
Date: Fri, 20 Oct 2017 02:55:57 +0200 [thread overview]
Message-ID: <1508460971-8731-1-git-send-email-frederic@kernel.org> (raw)
Checking whether IRQs are disabled or enabled is often an important
sanity check. Now we can be sometimes reluctant to have it on fastpath
because reading the flags can be somewhat costly.
As suggested by Peter Zijlstra some time ago, this would be a nice
lockdep extension: it's the natural concurrency sanity checker and it
already tracks down the irqflags state.
So here it is.

lockdep/irq
HEAD: 1cb58314de50c73eaf0b0322615ecb7a8ee39592
Thanks,
Frederic
