Careful, timespec will be different sizes in 32bit userspace and a 64bit

all the compat_timespec noise.  (I'd then also worry about padding and
might pack the struct.. I always lose track of the best practice across
all archs.)

Hmm we currently don't have ctree.h in ioctl.h. Can I include it there
or are there problems with that? As an alternative I could define my
own struct for that.

Hmm, yeah, it looks like ioctl.h is well isolated and doesn't really
have a precedent for pulling in format bits from the kernel

I'd do as you suggested and just make its own ioctl_timespec with a
comment that its duplicating other similar structures to keep ioctl.h
from getting tangled up in the kernel-side includes.
