[PATCH] add crtime to the snapshot list
From: Anand <anand.jain@oracle.com>
This patch adds creation-time to the snapshot list display,
which would help user to better manage the snapshots when
number of snapshots grow substantially. This patch is developed
and on top of the send/receive btrfs and btrfs-progs repo at
git://github.com/ablock84/linux-btrfs.git (send-v2)

[RFC PATCH 00/35] Xen i386 paravirtualization support
Unlike full virtualization in which the virtual machine provides
the same platform interface as running natively on the hardware,
paravirtualization requires modification to the guest operating system
to work with the platform interface provided by the hypervisor.
Xen was designed with performance in mind. Calls to the hypervisor
are minimized, batched if necessary, and non-critical codepaths
