From 17644a0bbb190b6286106e98392f3d60ee020a23 Mon Sep 17 00:00:00 2001 From: Jiufei Xue Date: Tue, 27 Feb 2018 20:10:03 +0800 Subject: block: fix the count of PGPGOUT for WRITE_SAME commit 7c5a0dcf557c6511a61e092ba887de28882fe857 upstream. The vm counters is counted in sectors, so we should do the conversation in submit_bio.
