[PATCH net-next 5/6] tcp: Simplify the allocation of slab caches

From: Kunwu Chan
Date: Mon Feb 05 2024 - 02:23:29 EST


Use the new KMEM_CACHE() macro instead of direct kmem_cache_create
to simplify the creation of SLAB caches.
And change cache name from 'tcp_bind_bucket' to 'inet_bind_bucket',
'tcp_bind2_bucket' to 'inet_bind2_bucket'.
