Yes. Ideally, ZFS would use FreeBSD's atomic operations instead of
its own. I believe that the reason it doesn't is (at least in part)
that we don't have 64-bit atomic operations for i386. I have
unfinished patches for cleaning up the atomic operations on all
platforms; I'll dust them off and see what I can do.
As I recall, Solaris 10 targets PPro and later processors, whereas
FreeBSD supports everything back to a 486DX. Hence we can't
assume that cmpxchg8b is available. The last time I remember this
coming up, people argued that we had to do things slow way in the
default kernel for compatibility.
Any ideas how ZFS and GEOM are going to work out, given that ZFS
is designed to be the filesystem + volume manager in one?
Anyway, this looks like awesome stuff! Unfortunately, I won't have
any time to play with it much in the short term, but as soon as WD
sends me the replacement for my spare disk I'll at least install
ZFS and see how it goes.
Awesome work, once again. Thanks!
