Bart Van Assche 63ce626d98 RDMA/srpt: Make slab cache names unique ... [ Upstream commit 4d784c042d ] Since commit 4c39529663 ("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().
