The following six patch series adds support to read vendor statistics for a vdpa device.
The first patch is just a cleanup fix. The second patch lays the ground to allow an upstream driver to provide statistics in the form of an attribute name/attribute value pairs.
The third and fourth patches make changes to locking scheme to use readers/writers semaphore instead if mutex.
The fifth patch implements this for mlx5_vdpa which gives received descriptors and completed descriptors information for all the virtqueues.
The sixth patch changes reslock mutex to readers/writers semaphore to achieve the same goal as done in vdpa core.
v7 -> v8: Convert cf_mutex to a rw_semaphore
Eli Cohen (6): vdpa: Fix error logic in vdpa_nl_cmd_dev_get_doit vdpa: Add support for querying vendor statistics net/vdpa: Use readers/writers semaphore instead of vdpa_dev_mutex net/vdpa: Use readers/writers semaphore instead of cf_mutex vdpa/mlx5: Add support for reading descriptor statistics vdpa/mlx5: Use readers/writers semaphore instead of mutex
