From 013ad043906b2befd4a9bfb06219ed9fedd92716 Mon Sep 17 00:00:00 2001 From: Mike Snitzer Date: Thu, 13 Sep 2018 21:16:20 -0400 Subject: dm thin metadata: fix __udivdi3 undefined on 32-bit sector_div() is only viable for use with sector_t. dm_block_t is typedef'd to uint64_t -- so use div_u64() instead.
