qed: Table, L2 cache, and cluster functions

This patch adds code to look up data cluster offsets in the image via
the L1/L2 tables. The L2 tables are writethrough cached in memory for
performance (each read/write requires a lookup so it is essential to
cache the tables)....

qed: Read/write support

This patch implements the read/write state machine. Operations are
fully asynchronous and multiple operations may be active at any time.

Allocating writes lock tables to ensure metadata updates do not
interfere with each other. If two allocating writes need to update the...

raw-posix: add discard support

Add support to discard blocks in a raw image residing on an XFS filesystem

hole punching mechanisms can be added when they become available.

(http://ceph.newdream.net/). This driver uses librados (which is part
of the Ceph server) for direct access to the Ceph object store and is
running entirely in userspace (Yehuda also wrote a driver for the...
