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

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:
http://lists.gnu.org/archive/html/qemu-devel/2014-07/msg03791.html
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
