[Qemu-devel] [PATCH 0/4] Split qcow2 driver

[Kevin Wolf <kwolf@redhat.com>]

The current qcow2 code is a monster of 3000 lines of code. This is hardly
manageable and doesn't exactly improve the driver's structure.

This patch series tries to split the driver in smaller modules. It doesn't
contain changes to functionality or structure, especially the latter might come
later as this series makes it much clearer what the internal interfaces used by
the qcow2 driver actually are.

The first three patches mainly move code around. They also build up a qcow2.h
header file which contains the common structs and functions used by several
modules. Some functions need to become global to keep things compilable.

The fourth patch cleans up the global namespace by adding a qcow2_ prefix to
all of the new global functions introduced by the first patches.

Kevin Wolf (4):
  qcow2: Split out refcount handling
  qcow2: Split out guest cluster functions
  qcow2: Split out snapshot functions
  qcow2: Rename global functions
