I've looked at this is some more detail and I think I can get away with just
asm-*/ioctl.h. The 2.6 one doesn't work because it checks the last argument to
_IOWR etc which in lvm.h is set to "1" rather than a datatype <sigh>. liblvm.h
also includes linux/genhd.h and linux/major.h which seem to be fairly clean for
further asm/ includes.
Maybe this will work. It seems OK on my PA box, I'll try Alpha tomorrow if I get
chance.
