The patch titled
lockdep: annotate 8390.c disable_irq()
has been removed from the -mm tree. Its filename is
lockdep-annotate-8390c-disable_irq.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: lockdep: annotate 8390.c disable_irq()
From: Ingo Molnar <mingo@xxxxxxx>
8390.c knows that ei_local->page_lock can only be used by an irq context that
it disabled - and can hence take the ->page_lock without disabling hardirqs.
Teach lockdep about this.
Has no effect on non-lockdep kernels.
