From cb38845d90fc4ad905aecd36ed85a75764d0b5fb Mon Sep 17 00:00:00 2001 From: Bart Van Assche Date: Tue, 14 Mar 2023 13:58:35 -0700 Subject: [PATCH] scsi: ufs: core: Set the residual byte count It is important for the SCSI core to know the residual byte count. Hence, extract the residual byte count from the UFS response and pass it to the SCSI core. A few examples of the output of a debugging patch that has been applied on top of this patch: [ 1.937750] cmd 0x12: len = 255; resid = 241 [ ... ] [ 1.993400] cmd 0xa0: len = 4096; resid = 4048 [ ... ] Signed-off-by: Bart Van Assche Link: https://lore.kernel.org/r/20230314205844.313519-1-bvanassche@acm.org Reviewed-by: Avri Altman Signed-off-by: Martin K.
