The main idea of this patch set is to call cache request not on kthread
upcall, but on userspace daemon cache_read call. This fixes the problem with
gaining of wrong dentry path after calling d_path() in kthread root context
(svc_export_request() callback), which always work in init root context, but
containers can work in "root jail" - i.e. have it's own nested root.

v2:
1) NFS DNS cache update wasn't done in the firest version. So this patch set
does preparation cleanup of the NFS DNS cache routines.
2) Also, this patch set doesn't remove cache_upcall helper anymore, because
it's still required for NFS DNS cache.

Argh--I really prefer incremental patches once I've already committed
something, but OK.


Sorry. I was thinking about incremental patches. Next time I'll do so.

Backing out the old patches, I'll take a look at these.  The first two
should probably get an ACK from Trond.


Trond, could you review first two patches, please?
They are just clean-ups, actually. Nothing special. Required to unify the interfaces for latter patches in the series.
