Subject: [PATCH v1 0/2] Synchronize user layer access with system PM ops and error handling
Date: Wed, 30 Dec 2020 20:25:33 -0800 [thread overview]
Message-ID: <1609388736-22525-1-git-send-email-cang@codeaurora.org> (raw)
This series contains two changes and it is based on 5.11/scsi-queue
The 1st change is just a minor fix.
The 2nd change is to synchronize user layer access through UFS sysfs nodes, so that system PM ops (suspend, resume and shutdown), error handling and async probe won't be disturbed by user layer access.
Can Guo (2):
scsi: ufs: Fix a possible NULL pointer issue
scsi: ufs: Protect PM ops and err_handler from user access through
sysfs
