Btrfs: PAGE_CACHE_SIZE is already unsigned long
PAGE_CACHE_SIZE == PAGE_SIZE is "unsigned long" everywhere, so there's no need to cast it to "unsigned long". Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org> Signed-off-by: Josef Bacik <jbacik@fusionio.com> Signed-off-by: Chris Mason <chris.mason@fusionio.com>
