From 10163cee1f06fc2e17bcf7bbc2982337202d1d5c Mon Sep 17 00:00:00 2001 From: Avri Altman Date: Sun, 8 Aug 2021 12:00:24 +0300 Subject: [PATCH] scsi: ufs: ufshpb: Do not report victim error in HCM In host control mode, eviction is perceived as an extreme measure. There are several conditions that both the entering and exiting regions should meet, so that eviction will take place. The common case however, is that those conditions are rarely met, so it is normal that the act of eviction fails. Therefore, do not report an error in host control mode if eviction fails.
