Changelog:
v0->v1:
- Addressed comments from Jason.
- Added accidentally removed xa_erase
- Moved free_netdevs() out of disable_device for wider use
- Replace refcount get/put from add_compat_devs with lock assert
- Added ibdev->dev get/put to hold on to device while net ns delete
- Corrected comments in __rdma_dev_change_netns for rename op
This series introduces a netlink command to change net namespace of a
rdma device. It performs small device disable enable sequence to ensure
that there is no active traffic when device moves to new namespace. This
operation needs to synchronize with device rename and device unregistration.
This is protected using recently introduced unregistration mutex.
When net namespace is deleted, all rdma devices residing in such net namespace
are moved back to default init_net namespace.
Thanks
