vfio: Fixes in iommufd vfio token handling

[PATCH v2 0/2] vfio: Fixes in iommufd vfio token handling

Posted by Raghavendra Rao Ananta 3 months, 1 week ago

Hello,

The series includes a couple of bug fixes that were accidentally
introduced as a part of VFIO's vf_token management for iommufd.

Patch-1: Fixes ksize arg while copying user struct in
vfio_df_ioctl_bind_iommufd.

Patch-2: Adds missing .match_token_uuid callback in
hisi_acc_vfio_pci_migrn_ops.

Thank you.
Raghavendra
