Is this the resend mail? Or a new version?
I replyed to your last mail.
THanks.

Rename vhost_scsi_iov_to_sgl to vhost_scsi_map_iov_to_sgl so it matches
matches the naming style used for vhost_scsi_copy_iov_to_sgl.

The linux block layer requires bios/requests to have lengths with a 512
byte alignment. Some drivers/layers like dm-crypt and the directi IO code
will test for it and just fail. Other drivers like SCSI just assume the
requirement is met and will end up in infinte retry loops. The problem
for driver
The write arg that's passed to the mapping functions is not used so
remove it.

The following patches were made over Linus's tree and fix an issue
where windows guests will send iovecs with offset/lengths that result
in IOs that are not aligned to 512. The LIO layer will then send them
to Linux's block layer but it requires 512 byte alignment, so depending
on the block driver

Yes, but probably SIGABRT/exi

Adding cond_resched() to the command waiting loop for a better
co-operation with the scheduler. This allows to give CPU a breath to
run other task(workqueue) instead of busy looping when preemption is
not allowed on a device whose CVQ might be slow.

This patch convert rx mode setting to be done in a workqueue, this is
a must for allow to sleep when waiting for the cvq command to
response since current code is executed under addr spin lock.

Hi all:
The code used to busy poll for cvq command which turns out to have
several side effects:
1) infinite poll for buggy devices
2) bad interaction with scheduler
So this series tries to use cond_resched() in the waiting loop. Before
doing this we need first make sure the cvq command is not e
