From be6e8dc0ba84029997075a1ec77b4ddb863cbe15 Mon Sep 17 00:00:00 2001 From: Balaji Rao Date: Mon, 21 Jul 2008 02:01:56 +0530 Subject: NFS support for btrfs - v3 Date: Mon, 21 Jul 2008 02:01:56 +0530 Here's an implementation of NFS support for btrfs. It relies on the fixes which are going in to 2.6.28 for the NFS readdir/lookup deadlock. This uses the btrfs_iget helper introduced previously.
