reads at just the right time is is possible to get duplicate output but
in practice this is extremely rare. Joint effort with Theo.

fstatfs(2), and getfsstat(2) so you will need to build a new kernel
before doing a "make build" or you will get "unimplemented syscall" errors.
The new struct statfs has the following featuires:
o Has a u_int32_t flags field--now softdep can have a real flag.
o Uses u_int32_t instead of longs (nicer on the alpha). Note: the man
page used to lie about setting invalid/unused fields to -1. SunOS does
that but our code never has.
o Gets rid of f_type completely. It hasn't been used since NetBSD 0.9
and having it there but always 0 is confusing. It is conceivable
that this may cause some old code to not compile but that is better
than silently breaking.
o Adds a mount_info union that contains the FSTYPE_args struct. This
means that "mount" can now tell you all the options a filesystem was
mounted with. This is especially nice for NFS.
Other changes:
o The linux statfs emulation didn't convert between BSD fs names
and linux f_type numbers. Now it does, since the BSD f_type
number is useless to linux apps (and has been removed anyway)
o FreeBSD's struct statfs is different from our (both old and new)
and thus needs conversion. Previously, the OpenBSD syscalls
were used without any real translation.
o mount(8) will now show extra info when invoked with no arguments.
However, to see *everything* you need to use the -v (verbose) flag.

to be vop_generic_revoke, vop_generic_bwrite, vop_generic_islocked,
vop_generic_lock and vop_generic_unlock.
Create vop_generic_abortop and propogate change to all file systems.
Fix PR/371.
Get rid of locking in NULLFS (should be mostly unnecessary now except for
forced unmounts).

[I built a new kernel fine, but don't have time to run "make build"
it is my intuition that this will not have any bad effects, but
I didn't test. Just back it out if it hurts you and I'll try again.]

OpenBSD define, not BSD which is a bit more useful.
