Subject: [patch 12/23] bkl: Fixup core_lock fallout
Date: Sun, 06 Dec 2009 18:02:53 -0000	[thread overview]
Message-ID: <20091206111957.768090168@linutronix.de> (raw)
In-Reply-To: 20091206110944.492100233@linutronix.de

[-- Attachment #1: bkl-core-lock-fixup.patch --]
[-- Type: text/plain, Size: 904 bytes --]

kernel_lock.c emits a warning because a raw spinlock function is used
with a spinlock. Convert BKL to raw_spinlock.
