Xen devel - Nov 2009 - linux-next: alacrity tree build failure

Hi Gregory,

Today''s linux-next build (x86_6 _allmodconfig) failed like this:

drivers/vbus/built-in.o:(.data+0x0): multiple definition of
`dev_attr_modalias''
drivers/xen/built-in.o:(.data+0x46d0): first defined here

Caused by commit 59aa8f441d27c8470764a513dafa46a77f33e953 ("vbus: add
autoprobe capability to guest").  The DEVICE_ATTR(modalias ...) should
probably be static.  I should probably be static in
drivers/xen/xenbus/xenbus_probe.c as well.

I have used the version of the alacrity tree from next-20091123 for today.

All those DEVICE_ATTR()s should be static in that case.  Indeed, I guess
they should be almost universally?  Should DEVICE_ATTR() include the
static?  (Hm, almost every instance in the kernel already has static; it
should probably have been part of the definition from the start, but
changing it now would cause a lot of churn.)

There are some "non static" usages, mostly to deal with stuff within a
module that takes more than one file.  They could probably all be fixed
up if someone really is bored :)

thanks,
