Subject: [PATCH 02/12] Add semaphore.h to kernel_lock.c
Date: Thu, 28 Feb 2008 01:33:51 -0500	[thread overview]
Message-ID: <1204180441-8540-2-git-send-email-matthew@wil.cx> (raw)
In-Reply-To: <1204180441-8540-1-git-send-email-matthew@wil.cx>

kernel_lock.c uses DECLARE_MUTEX, up() and down() without explicitly
including asm/semaphore.h.  This is fragile and leaves it vulnerable
to breakage during header reorganisations.
