Thanks Chengming Zhou,
As per my comment on a similar patch [*], this seems reasonable to me. But I think it would be best to post a v2 of this patch with the updated patch description (which is very helpful, BTW).

Also, while we are here, perhaps the indentation can be improved. Something like:
rpc_inode_cachep = kmem_cache_create("rpc_inode_cache", sizeof(struct rpc_inode), 0, (SLAB_HWCACHE_ALIGN|SLAB_RECLAIM_ACCOUNT| SLAB_ACCOUNT), init_once);
