nfsd: Simplify the allocation of slab caches in nfsd_drc_slab_create

KunWuChan · chucklever · commit 192d80cdcb4c · 2024-03-01T09:12:24.000-05:00
Use the new KMEM_CACHE() macro instead of direct kmem_cache_create
to simplify the creation of SLAB caches.
And change cache name from 'nfsd_drc' to 'nfsd_cacherep'.
