[PATCH v2 0/6] SUNPRC: cleanup PipeFS for network-namespace-awareusers

From: Stanislav Kinsbursky
Date: Mon Dec 26 2011 - 06:43:36 EST

This patch-set was created in context of clone of git
branch: git://git.linux-nfs.org/projects/trondmy/nfs-2.6.git.
tag: v3.2-rc7

1) rebased on tag "v3.2-rc7"
2) some cleanup and minor changes

This is cleanup precursor patch set. It's required for easier further
implementation of network-namespace-aware SUNRPC PipeFS pipes creators.
Generally, this patch set split SUNRPC PipeFS logic into two parts: working
with pipes (new rpc_pipe structure with link to PipeFS dentry) and
creating/destroying PipeFS dentries (old rpc_inode structure with link to
With this patch-set kernel PipeFS pipes users initially creates
rpc_pipe data and then creates Pipefs dentries. Later these dentries will be
created in notifier callbacks on PipeFS mount event from user-space and in
network namespace operations for such modules like nfs and blocklayout.

The following series consists of:


Stanislav Kinsbursky (6):
SUNRPC: replace inode lock with pipe lock for RPC PipeFS operations
SUNRPC: split SUNPRC PipeFS pipe data and inode creation
SUNRPC: cleanup PipeFS redundant RPC inode usage
SUNPRC: cleanup RPC PipeFS pipes upcall interface
SUNRPC: cleanup GSS pipes usage
SUNRPC: split SUNPRC PipeFS dentry and private pipe data creation
