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.
The following series implements...

Stanislav Kinsbursky (4): SUNRPC: introduce cache_detail->cache_request callback SUNRPC: remove cache_detail->cache_upcall callback SUNRPC: remove "cache_request" argument in sunrpc_cache_pipe_upcall() function SUNRPC: move cache_detail->cache_request callback call to cache_read()
