Tidy up the goto label in init(), and remove the useless
NULL pointer assignment.

Just use the macro instead of define a variable.

Use pr_err() instead of printk() for code cleanups.

patch 1-3,5 are some cleanups.
patch 4: create a separate work queue for virtio-scsi
to improve the performance, I tested with tmpfs backed
disk, the config file is like below,
[global]
bsrange=4k-64k
ioengine=libaio
direct=1
iodepth=4
loops=10
size=64M
Before:
Disk stats (read/write):
sda:
Fix a stack buffer overflow in the SCSI layer sysfs handling code
(store_host_reset()). When a host reset type is read via sscanf in str
there is no limit on the length and str is defined as char str[10].
How to reproduce:
Given that the sysfs entry exists, execute
echo

Nick,
Your company appears to be shipping kernel features in RTS OS that are
not made available under the GPL, specifically support for the
EXTENDED_COPY and COMPARE_AND_WRITE SCSI commands, in order to claim
full Vmware vSphere 5 VAAI support.

I think something else caused the improvement, because the code you
touched (complete_event) shouldn't ever run

Not quite.
Assuming the GPL applies, and that they have modified the code, then
they must
