This destroys any notion we have of global LRU-ness of inode and
dentry caches, doesn't it? Can you outline in more detail what sort
of reclaim pattern this results in. e.g. is a workload running on
a single node now effectively limited to a dentry/icache size within
the local node because of local node slab allocation and per-zone
reclaim?

Cheers,

Dave.
