[patch 54/71] xfs: fix spin_is_locked assert on uni-processor builds

[Greg KH]

2.6.30-stable review patch.  If anyone has any objections, please let us know.

------------------
From: Christoph Hellwig <hch@xxxxxxxxxxxxx>

upstream commit a8914f3a6d72c97328597a556a99daaf5cc288ae

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.
