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. Fixes: e3a35d03407c ("dm writecache: add event counters") Signed-off-by: Mikulas Patocka <mpatocka@redhat.com> Signed-off-by: Mike Snitzer <snitzer@kernel.org>
