Subject: [PATCH 1/2] IOMMU: correct parsing of "quarantine=scratch-page"
Date: Wed, 7 Jul 2021 15:21:51 +0200 [thread overview]
Message-ID: <dd85d77a-34c4-dbdf-1822-28612fe9f7ac@suse.com> (raw)
In-Reply-To: <95ceeea0-5623-952e-00c9-2c7f1a3459dc@suse.com>
During the multiple renames of the sub-option I apparently forgot to
update the left side of the &&, and this pretty consistently.
Fixes: 980d6acf1517 ("IOMMU: make DMA containment of quarantined devices optional")
Reported-by: Andrew Cooper <andrew.cooper3@citrix.com>
