Subject: [PATCH 0/2] Two fixes to vevent path
Date: Mon, 24 Mar 2025 05:00:32 -0700 [thread overview]
Message-ID: <20250324120034.5940-1-yi.l.liu@intel.com> (raw)
iommufd selftest occassionally fail when reading vevent. After debugging,
it is due to vevent->header.flags. It is not set properly per allocation.
This can be fixed by using kzalloc(). There is another related issue. The
veventq->num_events inc/dec is not balanced. This is problemtic. Make a
fix for it as well.
Regards,
Yi Liu
