Subject: [PATCH] xfs: fix spin_is_locked assert on uni-processor builds
Date: Mon, 10 Aug 2009 10:00:06 -0400 [thread overview]
Message-ID: <20090810140006.GA21521@infradead.org> (raw)
Without SMP or preemption spin_is_locked always returns false,
so we can't do an assert with it. Instead use assert_spin_locked,
which does the right thing on all builds.
This fixes kernel.org BZ #13621.
