      raw-posix: cleanup ioctl methods · 63ec93db
      由 Christoph Hellwig 提交于 
      Rename raw_ioctl and raw_aio_ioctl to hdev_ioctl and hdev_aio_ioctl as they
are only used for the host device.  Also only add them to the method table
for the cases where we need them (generic hdev if linux and linux CDROM)
instead of declaring stubs and always add them.

      block: add bdrv_probe_device method · 508c7cb3
      由 Christoph Hellwig 提交于 
      Add a bdrv_probe_device method to all BlockDriver instances implementing
host devices to move matching of host device types into the actual drivers.
For now we keep exacly the old matching behaviour based on the devices names,
although we really should have better detetion methods based on device
information in the future.

      raw-posix: split hdev drivers · f3a5d3f8
      由 Christoph Hellwig 提交于 
      Instead of declaring one BlockDriver for all host devices declared one
for each type:  a generic one for normal disk devices, a Linux floppy
driver and a CDROM driver for Linux and FreeBSD.  This gets rid of a lot
of messy ifdefs and switching based on the type in the various removal
device methods.

block.c grows a new method to find the correct host device driver based
on OS-sepcific criteria, which will later into the actual drivers in a
later patch in this series.

      raw-posix: add a raw_open_common helper · 90babde0
      由 Christoph Hellwig 提交于 
      raw_open and hdev_open contain the same basic logic.  Add a new
raw_open_common helper containing the guts of the open routine
and call it from raw_open and hdev_open.

We use the new open_flags field in BDRVRawState to allow passing
additional open flags to raw_open_common from both.

      raw-posix: always store open flags · 0e1d8f4c
      由 Christoph Hellwig 提交于 
      Both the Linux floppy and the FreeBSD CDROM host device need to store
the open flags so that they can re-open the device later.  Store the
open flags unconditionally to remove the ifdef mess and simply the
calling conventions for the later patches in the series.

      fix qemu_aio_flush · 986c28d6
      由 Andrea Arcangeli 提交于 
      qemu_aio_wait by invoking the bh or one of the aio completion
callbacks, could end up submitting new pending aio, breaking the
invariant that qemu_aio_flush returns only when no pending aio is
outstanding (possibly a problem for migration as such).
