Hi all,

These four patches make slight changes to the way QEMU handles SCSI
generic devices to fix a number of small problems.

I am sending them against the master branch, since I don't know if they
can be considered bugfixes.


v3 (rebased to current master):
* Avoid bit-rot in DPRINTF (adopt Eric's suggestion)
* Address Kevin's comments (DEBUF_FLOPPY, line > 80 chars, SG device)
* Mention Kevin's comment wrt disk flush in the corresponding commit

* remove duplicate check for sg inside iscsi_co_flush()
* remove DEBUG_BLOCK_PRINT in block/raw-posix.c
* use DPRINTF for debugging in block/raw-posix.c

PS: Paolo suggested to use a tracepoint inside hdev_is_sg() but I chose DPRINTF
instead. It would make sense to add a tracepoint for bdrv_is_sg() (just like
most bdrv_* commands) but this is too much for now since it just returns the
bs->sg flag (and is not an actual driver function). If you insist I'll change
it in v3.

Dimitris Aragiorgis (5):
  block: Use bdrv_is_sg() everywhere
  Fix migration in case of scsi-generic
  raw-posix: DPRINTF instead of DEBUG_BLOCK_PRINT
  raw-posix: Use DPRINTF for DEBUG_FLOPPY
  raw-posix: Introduce hdev_is_sg()
