lightweight C parsers much happier with the FreeBSD kernel
source, including cflow's prcc and lxr.

late stages of unmount). On failure, the vnode is recycled.
Add insmntque1(), to allow for file system specific cleanup when
recycling vnode on failure.
Change getnewvnode() to no longer call insmntque(). Previously,
embryonic vnodes were put onto the list of vnode belonging to a file
system, which is unsafe for a file system marked MPSAFE.
Change vfs_hash_insert() to no longer lock the vnode. The caller now
has that responsibility.
Change most file systems to lock the vnode and call insmntque() or
insmntque1() after a new vnode has been sufficiently setup. Handle
failed insmntque*() calls by propagating errors to callers, possibly
after some file system specific cleanup.

- Prefer '_' to ' ', as it results in more easily parsed results in
memory monitoring tools such as vmstat.
- Remove punctuation that is incompatible with using memory type names
as file names, such as '/' characters.
- Disambiguate some collisions by adding subsystem prefixes to some
memory types.
- Generally prefer lower case to upper case.
- If the same type is defined in multiple architecture directories,
attempt to use the same name in additional cases.
Not all instances were caught in this change, so more work is required to
finish this conversion. Similar changes are required for UMA zone names.

it to get better hashing in vfs_hash.
In case of an insert collision in vfs_hash_insert(), put the loosing vnode
on a special list so that vfs_hash_remove() can just assume that it is on
a list.
Drop the VI_HASHED flag.

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.
