that we free that resource. All the other resources are freed in
their own routine, but since we haven't saved a pointer to this one,
it is leaked. This is the failure case that lead to the sio ports
that weren't working, I think.
Currently implemented are most things related to states and interfaces, todo
are address tables and altq. I've tried to keep this roughly in sync with a
project implementing this for net-snmpd.

sys/bus_dma.h instead of being copied in every single arch. This slightly
reorders a flag that was specific to AXP and thus changes the ABI there.
The interface still relies on bus_space definitions found in <machine/bus.h>
so it cannot be included on its own yet, but that will be fixed at a later
date. Add an MD <machine/bus_dma.h> for ever arch for consistency and to
allow for future MD augmentation of the API. sparc64 makes heavy use of
this right now due to its different bus_dma implemenation.
as suggested by Matt's comment. Also fix some style and paranoia issues.
The entire function could benefit from review by a VFS guru.

Since we used an sbuf of size resid to accumulate dirents, we would end
up returning one byte short when we had enough dirents to fill or exceed
the size of the sbuf (the last byte being lost to bogus NUL termination)
causing the next call to return EINVAL due to an unaligned offset. This
went undetected for a long time because I did most of my testing in
single-user mode, where there are rarely enough processes to fill the
4096-byte buffer ls(1) uses. The most common symptom of this bug is that
tab completion of /proc or /compat/linux/proc does not work properly when
many processes are running.
Also, a check near the top would return EINVAL if resid was smaller than
PFS_DELEN, even if it was 0, which is frequently the case and perfectly
allowable. Change the test so that it returns 0 if resid is 0.

usage for a subcommand, so no 'usage' function has to be implemented
in class library.
- Bump version number as it breaks ABI, but don't provide backward
compatibility, because there are probably no external consumers of this
geom(8).
This allows to print more precise usage for standard commands and simplify
class libraries a bit.

to get from (mount + inode) to vnode. These tables are mostly
copy&pasted from UFS, sized based on desiredvnodes and therefore
quite large (128K-512K). Several filesystems are buggy enough that
they allocate the hash table even before they know if they will
ever be used or not.
Add "vfs_hash", a system wide hash table, which will replace all
the per-filesystem hash-tables.
The fields we add to struct vnode will more or less be saved in
the respective filesystems inodes.
Having one central implementation will save code and will allow us
to justify the complexity of code to dynamically (re)size the hash
at a later point.
to use only the holdcnt to determine whether a vnode may be recycled,
simplifying the V* macros as well as vtryrecycle(), etc.
