Jason Wang 69ec350a41 vdpa: mlx5: prevent cvq work from hogging CPU ... [ Upstream commit 55ebf0d60e ] A userspace triggerable infinite loop could happen in mlx5_cvq_kick_handler() if userspace keeps sending a huge amount of cvq requests. Fixing this by introducing a quota and re-queue the work if we're out of the budget (currently the implicit budget is one) . While at it, using a per device work struct to avoid on demand memory allocation for cvq.
