From: Liu Yuan <tailai...@taobao.com> Trim/discard is a command that allows VM to inform underlying storage system to release unused space. Sheepdog takes use of this command to release unused objects for better thin-provision.
This patch set aims to add trim/discard support to both Sheepdog and QEMU's Sheepdog block driver. There are first 3 patches for Sheepdog and the last one is for QEMU. Thanks, Yuan -- 1.7.9.5
