dm thin metadata: fix __udivdi3 undefined on 32-bit
commit 013ad043906b2befd4a9bfb06219ed9fedd92716 upstream. sector_div() is only viable for use with sector_t. dm_block_t is typedef'd to uint64_t -- so use div_u64() instead. Fixes: 3ab918281 ("dm thin metadata: try to avoid ever aborting transactions") Signed-off-by: Mike Snitzer <snitzer@redhat.com> Cc: Sudip Mukherjee <sudipm.mukherjee@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
