Subject: [PATCH] block: copy ioprio in __bio_clone_fast()
References: bsc#1082653
Git-commit: ca474b73896bf6e0c1eb8787eb217b0f80221610
Patch-Mainline: v4.20-rc3
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")
