From ca474b73896bf6e0c1eb8787eb217b0f80221610 Mon Sep 17 00:00:00 2001 From: Hannes Reinecke Date: Mon, 12 Nov 2018 10:35:25 -0700 Subject: block: copy ioprio in __bio_clone_fast() and bounce We need to copy the io priority, too; otherwise the clone will run with a different priority than the original one. Fixes: 43b62ce3ff0a ("block: move bio io prio to a new field") Signed-off-by: Hannes Reinecke Signed-off-by: Jean Delvare Fixed up subject, and ordered stores.
