From 2ee73ef60db4d79b9f9b8cd501e8188b5179449f Mon Sep 17 00:00:00 2001 From: Mikulas Patocka Date: Mon, 11 Jul 2022 16:31:52 -0400 Subject: dm writecache: count number of blocks discarded, not number of discard bios Change dm-writecache, so that it counts the number of blocks discarded instead of the number of discard bios. Make it consistent with the read and write statistics counters that were changed to count the number of blocks instead of bios.
