[Qemu-devel] [PATCH v5 0/4] qemu-img: add preallocation=full

[Hu Tao <hutao@cn.fujitsu.com>]

From: Your Name <you@example.com>

This series implements full image preallocation to create a non-sparse image
file at creation time, both for raw and qcow2 format. The purpose is to avoid
performance deterioration of the guest cause by sparse image.

v5:
  - fix wrong calculation of qcow2 metadata size in v4
  - remove raw_preallocate2()
  - better error out path in raw_create()
  - fix coding style

Hu Tao (4):
  qapi: introduce PreallocMode and a new PreallocMode full.
  raw, qcow2: don't convert file size to sector size
  raw-posix: Add full image preallocation option
  qcow2: Add full image preallocation option
