[Qemu-devel] [PATCH 0/4] Geometry and blocksize support for backing devices

[Ekaterina Tumanova]

This patch set is based on a patch suggested by Einar Lueck
on Feb 08, 2013.

This patch set introduces:
1. s390x specific geometry detection:
Add s390 specific version of hd_geometry_guess function,
which uses HDIO_GETGEO ioctl.

2. A set of blocksize patches for autodetection of logical and
physical blocksizes. Change history:
2.1
Original blocksize patch only configured autolookup for
virtio-blk devices. There was a request from Stefan Hajnoczi
to make this architecture-independent. Now autolookup is
configured by default for all block devices.
2.2
Add driver method to probe blocksizes for "raw" and
"host_device" drivers.
(also requested by the reviewers of the original patch)

Ekaterina Tumanova (4):
  hd-geometry.c: Integrate HDIO_GETGEO in guessing for target-s390x
  blocksize: support auto-sensing of blocksizes
  blocksize: Add driver method to get the blocksizes
  blocksize: add blkconf_blocksize call to all block devices
