Log:
struct drive:
Workaround size mismatch in struct drive on alpha platform only.
This struct is shared between kernel and userland and contains a
dev_t, which now refers to a completely different structure in
userland and kernel: int the kernel, userland dev_t is called
udev_t, and dev_t is struct specinfo *. In practical terms, kernel
dev_t is a pointer and userland dev_t is an int, which on the alpha
are different sizes.
As stated, this is a workaround. The correct fix would be in two
parts:
1. Don't define structures in the kernel with the same name and a
different content as a userland structure. This is a
kernel-wide issue: kernel dev_t needs another name.
2. Don't export unnecessary kernel structures to userland. This
can be done within Vinum. It is currently on the tuit queue.
