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);
