v3:
- use false instead of 0

v2:
- update macro
- update inode before remove_object()

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.

Thanks,
Yuan
