Subject[PATCH v2 0/4] SUNRPC: several fixes around PipeFS objects
From
Date
v2: 
1) Prior to calling PipeFS dentry rountines (for both type of clients - SUNPRC
and NFS) get the client and drop the list lock instead of replacing per-net
locks by mutexes.

First two pathes fixes lockdep warnings and next two - dereferencing of
released pipe data on eventfd close and in file operations.

The following series consists of:

---
Stanislav Kinsbursky (4):
SUNRPC: release per-net clients lock before calling PipeFS dentries creation
NFS: release per-net clients lock before calling PipeFS dentries creation
SUNRPC: check RPC inode's pipe reference before dereferencing
SUNRPC: move waitq from RPC pipe to RPC inode
