Subject[PATCH v2 vfio 0/3] pds/vfio: Fixes for locking bugs
Date
This series contains fixes for locking bugs in the recently introduced
pds-vfio-pci driver. There was an initial bug reported by Dan Carpenter
at:

https://lore.kernel.org/kvm/1f9bc27b-3de9-4891-9687-ba2820c1b390@moroto.mountain/

However, more locking bugs were found when looking into the previously
mentioned issue. So, all fixes are included in this series.

v2:
https://lore.kernel.org/kvm/20230914191540.54946-1-brett.creeley@amd.com/
- Trim the OOPs in the patch commit messages
- Rework patch 3/3 to only unlock the spinlock once
- Destroy the state_mutex in the driver specific vfio_device_ops.release
callback

Brett Creeley (3):

pds/vfio: Fix mutex lock->magic != lock warning
