Btrfs: Make btrfs_header_fsid() return unsigned long
Internally, btrfs_header_fsid() calculates an unsigned long, but casts it to a pointer, while all callers cast it to unsigned long again. 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>
