RDMA/srpt: Make slab cache names unique
Since commit 4c39529663b9 ("slab: Warn on duplicate cache names when
DEBUG_VM=y"), slab complains about duplicate cache names. Hence this
patch. The approach is as follows:
- Maintain an xarray with the slab size as index and a reference count
and a kmem_cache pointer as contents. Use srpt-${slab_size} as kmem
cache name.
- Use 512-byte alignment for all slabs instead of only for some of the
slabs.
- Increment the reference count instead of calling kmem_cache_create().
- Decrement the reference count instead of calling kmem_cache_destroy().
