Field "layerm_vfs" of "struct layer_mount" got superseded by "mnt_lower".
Adapt consumers and remove the now unused field.

Slightly clean-up layerfs and nullfs: update the big description more to
the reality (remove duplicate one in nullfs, merge some differences from
it), KNF, improve and update some comments, add few KASSERT()s, remove
unused declarations, avoid double inclusion of headers, misc.

No functional changes.

Create sysctl entries during module initialisation and destroy them
appropriately.

Many of these file systems are now ready for modularisation.

merge ktrace-lwp.

Remove __P()

Tweak sysctl setup functions (the macros, actually) for use in lkms,
and tweak lkminit_*.c (where applicable) to call them, and to call
sysctl_teardown() when being unloaded.

This consists of (1) making setup functions not be static when being
compiled as lkms (change to sys/sysctl.h), (2) making prototypes
visible for the various setup functions in header files (changes to
various header files), and (3) making simple "load" and "unload"
functions in the actual lkminit stuff.

linux_sysctl.c also needs its root exposed (ie, made not static) for
this (when built as an lkm).

Move UCB-licensed code from 4-clause to 3-clause licence.

Patches provided by Joel Baker in PR 22364, verified by myself.

Wrap long line and remove name of argument from function prototype.

Introduce layer library in genfs. This set of files abstracts most of
the functionality of nullfs. The latter is now just a mount & unmount
routine, and a few tables. umapfs borrow most of this infrastructure.

Both fs's are now nfs-exportable.

All layered fs's share a common format to private mount & private
vnode structs (which a particular fs can extend).

Also add genfs_noerr_rele(), a vnode op which will vrele/vput
operand vnodes appropriately.

Make the vfs ops and vnodeop_opv symbols match the name of the
file-system option used to configure the file system into the kernel.

don't try to use __builtin_return_address() on the Alpha. (It's never
worked as far as I can tell, and apparently crashes the kernel when
invoked here.) From Ross Harvey, PR#3471.

Allow the DIAGNOSTIC to compile with old versions of gcc.

Add locking code to avoid deadlocks on vnode reclaim, which means the
addition of null_lookup, null_lock, null_unlock, null_islocked.

miscfs prototype changes

KERNEL -> _KERNEL

Convert hash tables.

New RCS ID's, take two. they're more aesthecially pleasant, and use 'NetBSD'

Update to 4.4-Lite fs code, with local changes.
