Eliminate unnecessary KASSERTs.

Don't use bp->b_vp in VOP_STRATEGY: the vnode is passed in as an argument.

Make the udf_vnops side endian clean.

First half of making UDF be endian-clean. This addresses the vfsops side.

Catch all cases where bread() returns an error and a valid *bp, and release
the *bp.

DuH!

bp->b_iooffset (the spot on the disk), not bp->b_offset (the offset in
the file)

Initialize b_offset before calling VOP_STRATEGY/VOP_SPECSTRATEGY.

Remove various comments of KASSERTS and comments about B_PHYS which
does not apply anymore.

- Don't cache_purge() in *_reclaim routines. vclean() does it for us so
this is redundant.

Add the same KASSERT to all VOP_STRATEGY and VOP_SPECSTRATEGY implementations
to check that the buffer points to the correct vnode.

Correctly calculate the size of the extent that should be read in
udf_readatoffset(). This should fixe problems with reading udf filesystems
created with mkisofs.

Implement the node cache as a hash table.

Make udf_allocv() return an unlocked vnode instead of a locked one
to avoid a "locking against myself" panic when udf_hashins() tries
to lock it again. Lock the vnode in udf_hashins() before adding i

Temporarily introduce a new VOP_SPECSTRATEGY operation while I try
to sort out disk-io from file-io in the vm/buffer/filesystem space.

The intent is to sort VOP_STRATEGY calls into those which operate
on "real" vnodes and those which operate on VCHR vnodes. For
the latter kind, the call will be changed to VOP_SPECSTRATEGY,
possibly conditionally for those places where dual-use happens.

Add a default VOP_SPECSTRATEGY method which will call the normal
VOP_STRATEGY. First time it is called it will print debugging
information. This will only happen if a normal vnode is passed
to VOP_SPECSTRATEGY by mistake.

Add a real VOP_SPECSTRATEGY in specfs, which does what VOP_STRATEGY
does on a VCHR vnode today.

Add a new VOP_STRATEGY method in specfs to catch instances where
the conversion to VOP_SPECSTRATEGY has not yet happened. Handle
the request just like we always did, but first time called print
debugging information.

Apart up to two instances of console messages per boot, this amounts
to a glorified no-op commit.

If you get any of the messages on your console I would very much
like a copy of them mailed to phk@freebsd.org

Regularize the vop_stdlock'ing protocol across all the filesystems
that use it. Specifically, vop_stdlock uses the lock pointed to by
vp->v_vnlock. By default, getnewvnode sets up vp->v_vnlock to
reference vp->v_lock. Filesystems that wish to use the default
do not need to allocate a lock at the front of their node structure
(as some still did) or do a lockinit. They can simply start using
vn_lock/VOP_UNLOCK. Filesystems that wish to manage their own locks,
but still use the vop_stdlock functions (such as nullfs) can simply
replace vp->v_vnlock with a pointer to the lock that they wish to
have used for the vnode. Such filesystems are responsible for
setting the vp->v_vnlock back to the default in their vop_reclaim
routine (e.g., vp->v_vnlock = &vp->v_lock).

In theory, this set of changes cleans up the existing filesystem
lock interface and should have no function change to the existing
locking scheme.

2. The user of VT_PROCFS now checks for the new flag VV_PROCDEP, which
is propagated by pseudofs to all child vnodes if the fs sets PFS_PROCDEP.
