From: Anand Jain <anand.jain@oracle.com> (This patch is for the review/test not yet for the integration). Here is an implementation of the feature to add label to the subvolume and snapshots. Which would help sysadmin to better manager the subvol and snapshots. This can be done in two ways, one - using attr which is user land only changes but drawback is able to change the label

Hi, The following patches add support for ext4 and btrfs to PV-GRUB. These patches are taken nearly verbatim from those provided by Fedora and Gentoo.

Changes from v1: - Makefile has been changed to check the exit code from patch - The btrfs patch has been rebased to apply

The patchset has grown to 65 patches. 46 of them
