Hi,

because after just a first glance this patch seems wrong as the tmp variables
cannot be used beyond the first tcg_gen_cond() (conditional branches clobber
temporary vars), you must use tcg_temp_local_new() and tcg_temp_free().

Isn't is better to move "name[0] == '\0'" check to
bdrv_create_dirty_bitmap, near existed name checking?

v1 was: "add watermark reporting for block devices", but
"watermark" is incorrectly unused. Hence the change in subject.
Sorry for long pause from v1 [0];
Only recently I was able to sort out all the missing details.
Context for this RFC/patch is presented below as remider.
Why RFC?
See
Managing applications, like oVirt (http://www.ovirt.org), make extensive
use of thin-provisioned disk images.
To let the guest run smoothly and be not unnecessarily paused, oVirt sets
a disk usage threshold (so called 'high water mark') based on the occupation
of the device, and automatically exte

Hello, all
I am reviewing source of Qemu. I can see parameter called "opaque" from a lot
of function like this:
//@hw/timer/xilinx_timer.c
static uint64_t timer_read(void *opaque, hwaddr addr, unsigned int size)
{
...
}
, and its meaning confuse me. What does "opaque" stand for?
Thanks,
Kai
When bs->filename and bs->backing_file are relative pathname and not under the
same directory, path_combine() can not give the correct path for
bs->backing_file. So add get_localfile_absolute_path to get absolute path for
local file.
e.g:
$ pwd
/tmp
$ /opt/qemu-git-arm/bin/qemu-img create -f qcow2

Old BIOSes left some padding by mistake after the req_size/resp_size.
New QEMU does not like it, thinking it is a bidirectional command.
As a workaround, we can check if the ANY_LAYOUT bit is set; if not, we
always consider the first buffer as the virtio-scsi request/response,
