Subject: [PATCH v1 0/6] Complementary changes for error handling
Date: Wed, 12 May 2021 22:55:12 -0700 [thread overview]
Message-ID: <1620885319-15151-1-git-send-email-cang@codeaurora.org> (raw)
Commit cb7e6f05fce67c965194ac04467e1ba7bc70b069 ("scsi: ufs: core: Enable
power management for wlun") makes the UFS device W-LU the supplier, based
on which we need to make some changes to accomodate error handling.
This series is tested by fault injections (to IRQ handler, UIC cmds and
task abort where error handler can possibley be invoked) in all possible
contexts, e.g., scaling, gating, runtime and system suspend/resume.
Below changes are tested as a whole and based on 5.14/scsi-queue.
Can Guo (6):
scsi: ufs: Differentiate status between hba pm ops and wl pm ops
scsi: ufs: Update the return value of supplier pm ops
scsi: ufs: Simplify error handling preparation
scsi: ufs: Update ufshcd_recover_pm_error()
scsi: ufs: Let host_sem cover the entire system suspend/resume
scsi: ufs: Update the fast abort path in ufshcd_abort() for PM
requests
