[PATCH] dm mirror log: bitset_size fix
Fix the 'sizeof' in the region log bitmap size calculation: it's uint32_t, not unsigned long - this breaks on some archs. Signed-off-by: Alasdair G Kergon <agk@redhat.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
