Description
The Video for Linux v2 API suffers from the same problem as RDMA vs DAX,
i.e. it wants to established long lived memory registrations. Add a
semantic that allows the kernel to revoke access to the registration so
that the elevated page counts are time bounded.
Target Kernel: 4.19
- Target Release: 18.10
+ Target Release: 19.04
