Subject: [PATCH AUTOSEL 6.6 07/15] loop: aio inherit the ioprio of original request

From: Yunlong Xing <yunlong.xing@...soc.com>

[ Upstream commit 1fdb8188c3d505452b40cdb365b1bb32be533a8e ]

Set cmd->iocb.ki_ioprio to the ioprio of loop device's request.
The purpose is to inherit the original request ioprio in the aio
flow.
