Subject: Re: [PATCH v2 0/2] ufs: fix POST_CHANGE pairing and AHIT race condition
Date: Fri, 25 Sep 2026 22:30:38 -0400 [thread overview]
Message-ID: <yq1jyo8pwwc.fsf@mail.kernel.org> (raw)
In-Reply-To: <20260914085148.136429-1-peter.wang@mediatek.com>
> Patch 1 fixes a bug where POST_CHANGE was skipped on a failed gear
> switch, leaving the host in an inconsistent state if resources acquired
> in PRE_CHANGE were never released.
>
> Patch 2 fixes a race between the sysfs AHIT update path and the
> MediaTek host driver's power mode change path. A mutex and depth
> counter are introduced to serialize AHIT register access and ensure
> AHIT is correctly restored after the last disabler completes.
Applied to 7.4/scsi-staging, thanks!
