[dm-devel] [PATCH] 2.4: kcopyd.c: fix "flags" parameter to spin_lock_irqsave()

[Kevin Corry]

In kcopyd.c, change the "flags" arguments to the spin_lock_irqsave() calls
to unsigned long's. Most architectures don't mind an int, but ppc64 gives
compiler warnings (ppc32 and x86_64 likely will as well).
