Subject[PATCH v8 0/6] Show statistics for a vdpa device
Date
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

net/vdpa: Use readers/writers semaphore instead of cf_mutex
