Date: Mon, 11 Aug 2008 12:02:34 +0400 From: "Denis V. Lunev" <den@...nvz.org> To: akpm@...ux-foundation.org Cc: linux-kernel@...r.kernel.org, linux-nfs@...r.kernel.org, "Denis V. Lunev" <den@...nvz.org>, Trond Myklebust <Trond.Myklebust@...app.com>, "J. Bruce Fields" <bfields@...ldses.org> Subject: [PATCH 1/1] nfs: BUG_ON in nfs_follow_mountpoint Unfortunately, BUG_ON(IS_ROOT(dentry)) can happen inside nfs_follow_mountpoint with NFS running Fedora 8 using a specific setup. https://bugzilla.redhat.com/show_bug.cgi?id=458622 So, the situation should be handled on NFS client gracefully.
