This is a note to let you know that I have just added a patch titled vfs: d_obtain_alias() needs to use "/" as default to the linux-3.5.y-queue branch of the 3.5.y.z extended stable tree which can be found at: http://kernel.ubuntu.com/git?p=ubuntu/linux.git;a=shortlog;h=refs/heads/linux-3.5.y-queue If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.5.y.z tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Herton ------ From 0cc92e888494c489a4f6b91b072718a1f3626216 Mon Sep 17 00:00:00 2001 From: NeilBrown <neilb@suse.de> Date: Thu, 8 Nov 2012 16:09:37 -0800 Subject: [PATCH 22/27] vfs: d_obtain_alias() needs to use "/" as default name. commit b911a6bdeef5848c468597d040e3407e0aee04ce upstream. NFS appears to use d_obtain_alias() to create the root dentry rather than d_make_root. This can cause 'prepend_path()' to complain that the root has a weird name if an NFS filesystem is lazily unmounted. e.g. if "/mnt" is an NFS mount then { cd /mnt; umount -l /mnt ; ls -l /proc/self/cwd; } will cause a WARN message like WARNING: at /home/git/linux/fs/dcache.c:2624 prepend_path+0x1d7/0x1e0() ... Root dentry has weird name <> to appear in kernel logs. So change d_obtain_alias() to use "/" rather than "" as the anonymous name.
