    SUNRPC: handle RPC client pipefs dentries by network namespace aware routines · 0157d021
    Stanislav Kinsbursky authored
    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().
