[PATCH 1/2] xen: Populate xenbus device attributes
The xenbus bus type uses device_create_file to assign all used device
attributes. However it does not remove them when the device goes away.
This patch uses the dev_attrs field of the bus type to specify default
attributes for all devices.

[PATCH 0/13 v7] PCI: Linux kernel SR-IOV support
Greetings,
Following patches are intended to support SR-IOV capability in the
Linux kernel. With these patches, people can turn a PCI device with
the capability into multiple ones from software perspective, which
will benefit KVM and achieve other purposes such as QoS, security,
and etc.
The Physical Function and Virtual Function drivers using the SR-IOV
APIs will come soon!

[PATCH][BLKBACK] Clean code by VBD_SHOW macro in xenbus.c
This patch is cleaning code in xenbus.c by VBD_SHOW macro.
VBD_SHOW macro can be applied show functions with corresponded to
''physical_devices'' and ''mode'' attributes.
And corresponding ''device_create_file'' and ''device_remove_file'' function can be inserted
into ''xenvbd_sysfs_addif'' and ''xenvbd_sysfs_delif functions'' too.
So, this patch transfer code based on above reasons.
Thereby, code will be clear.
Thanks,
Satoshi UCHIDA
