[PATCH v3 1/7] SUNRPC: create RPC pipefs superblock per network namespace context
From: Stanislav Kinsbursky <hidden>
Date: 2011-12-26 11:39:21
Also in:
linux-nfs, lkml
Subsystem:
kernel nfsd, sunrpc, and lockd servers, networking [general], nfs, sunrpc, and lockd clients, the rest · Maintainers:

This is the initial step of RPC pipefs virtualization. It changes nothing to current pipefs behaviour except that mount of pipefs in other than init_net network namespace context will provide only root tree. No other dentries will be visible.
