Applied to misc-next, thanks!
I've tested v7 with a different capsets, works well. For a non-VT FB the
vmap indeed will be needed. Looking forward to the atomic vmap support.
The rough idea of the atomic vmap helper is to make vmap code paths fail
whenever hitting path that needs to sleep. Likely will be easy to implement.
Thanks for your support.
I will see if we can do something for atomic vmap support for shmem.
Best regards,
