From 2561d618ffb615f92fe17f0cf6b03f8e5cddb2cb Mon Sep 17 00:00:00 2001 From: Stanislav Kinsbursky Date: Tue, 10 Jan 2012 17:04:40 +0400 Subject: [PATCH] NFS: remove RPC PipeFS mount point reference from blocklayout routines This is a cleanup patch. We don't need this reference anymore, because blocklayout pipes dentries now creates and destroys in per-net operations and on PipeFS mount/umount notification. Note that nfs4blocklayout_register_net() now returns 0 instead of -ENOENT in case of PipeFS superblock absence. This is ok, because blocklayout pipe dentry will be created on PipeFS mount event.
