[Qemu-devel] [PATCH v2 0/6] Geometry and blocksize support for backing devices

[Ekaterina Tumanova]

Hi folks,

I'm sorry for the recent spam. I messed up during code submission last time.
So please ignore any previous notes you received from me and answer only to
this thread.

This is the rework of the geometry+blocksize patch, which was
recently discussed here:
http://lists.gnu.org/archive/html/qemu-devel/2014-11/msg01148.html

Markus suggested that we only detect blocksize and geometry for DASDs.

According to this agreement new version contains DASD special casing.
The driver methods are implemented only for "host_device" and inner hdev_xxx
functions check if the backing storage is a DASD by means of
BIODASDINFO2 ioctl.

Original patchset can be found here:

Ekaterina Tumanova (6):
  geometry: add bdrv functions for geometry and blocksize
  geometry: Detect blocksize via ioctls in separate static functions
  geometry: Add driver methods to probe blocksizes and geometry
  geometry: Add block-backend wrappers for geometry probing
  geometry: Call backend function to detect geometry and blocksize
  geometry: Target specific hook for s390x in geometry guessing
