Subject: [PATCH v2] scsi/sd: Fix Opal support
Date: Sun, 21 Feb 2021 18:10:42 -0800	[thread overview]
Message-ID: <20210222021042.3534-1-bvanassche@acm.org> (raw)

The SCSI core has been modified recently such that it only processes PM
requests if rpm_status != RPM_ACTIVE. Since some Opal requests are
submitted while rpm_status != RPM_ACTIVE, set flag RQF_PM for Opal
requests.

See also https://bugzilla.kernel.org/show_bug.cgi?id=211227.

Fixes: d80210f25ff0 ("sd: add support for TCG OPAL self encrypting disks")
Fixes: 271822bbf9fe ("scsi: core: Only process PM requests if rpm_status != RPM_ACTIVE")
