Re: [PATCH rdma v9 4/7] RDMA/zrdma: Add hardware resource initialization and verbs skeleton

[sashiko-bot@kernel.org]

> Implement hardware resource initialization logic and provide a minimal
> but functional verbs layer skeleton. This includes basic device
> registration with the minimal set of device ops (owner, driver_id,
> uverbs_abi_ver), to satisfy the requirement that the driver must be
> functional and have a valid driver ID.
> 
> The hardware resources of the driver are held in a single allocation,
> which carries the allocation bitmaps of the resource pools. The first
> entry of the memory region, protection domain, queue pair, address
> handle and multicast group pools is reserved.
> 
> The device ops are exported so that the probe path can install them
> right after ib_alloc_device(). When the resource memory cannot be
> allocated, the 8K index counter array is released with a cleared
> pointer, so that the dealloc hook does not free the same allocation
> twice.
