From 0157d021d23a087eecfa830502f81cfe843f0d16 Mon Sep 17 00:00:00 2001 From: Stanislav Kinsbursky Date: Wed, 11 Jan 2012 19:18:01 +0400 Subject: SUNRPC: handle RPC client pipefs dentries by network namespace aware routines v2: 1) "Over-put" of PipeFS mount point fixed. Fix is ugly, but allows to bisect the patch set. And it will be removed later in the series. This patch makes RPC clients PipeFs dentries allocations in it's owner network namespace context. RPC client pipefs dentries creation logic has been changed: 1) Pipefs dentries creation by sb was moved to separated function, which will be used for handling PipeFS mount notification. 2) Initial value of RPC client PipeFS dir dentry is set no NULL now. RPC client pipefs dentries cleanup logic has been changed: 1) Cleanup is done now in separated rpc_remove_pipedir() function, which takes care about pipefs superblock locking. Also this patch removes slashes from cb_program.pipe_dir_name and from NFS_PIPE_DIRNAME to make rpc_d_lookup_sb() work. This doesn't affect vfs_path_lookup() results in nfs4blocklayout_init() since this slash is cutted off anyway in link_path_walk().
