Hi Michael,
I see you dropped these patches from v1 to v2. Just checking if this
was intended or if there is an issue/CI failure that needs addressing?
[...]
Dorinda Bassey (1):
vhost: Fix SHMEM_MAP transaction ordering and resulting deadlock
Feifan Qian (1):
vhost-user: Reject SHMEM_MAP when no KVM memory slot is left
[...]
Matej Hrica (2):
vhost-user-gpu: Add shared memory region support
vhost-user-gpu: Forward RESOURCE_BLOB and CONTEXT_INIT flags
[...]
Thanks!
Albert
