Subject: [PATCH for-next 0/5] scsi: hisi_sas/libsas: Fix SATA devices missing issue during hisi_sas_debug_I_T_nexus_reset()
Date: Fri, 18 Nov 2022 16:37:09 +0800 [thread overview]
Message-ID: <20221118083714.4034612-1-zhanjie9@hisilicon.com> (raw)
SATA devices on an expander may be removed and not be found again
when I_T nexus reset and revalidation are processed simultaneously,
which is probable to happen in hisi_sas_clear_nexus_ha().
The issue came up since commit 71453bd9d1bf ("scsi: hisi_sas: Use
sas_ata_wait_after_reset() in IT nexus reset"), where the ex_phy's
change count is updated in hisi_sas_debug_I_T_nexus_reset(), stopping
future revalidation from discovering the SATA devices after link
reset.
This patchset fixes the issue.

HA reset"

scsi: libsas: Do not export sas_ata_wait_after_reset()
