Re: [Xen-devel] iSCSI root

[Keir Fraser <Keir.Fraser@xxxxxxxxxxxx>]

That's a rather odd thing to do, as it's not like there's a generic
EXPORT_SYMBOL'ed way to e.g. open a file. I can't imagine why they'd
have removed all wrappers except execve.

Easiest workaround is just to roll your own wrappers around the
syscalls using the _syscall* macros.
