P_*/L_* naming convention, and rename the in-kernel flags to avoid
conflict. (P_ -> PK_, L_ -> LW_ ). Add back the (now unused) LSDEAD
constant.
Restores source compatibility with pre-newlock2 tools like ps or top.

process we're trying to get information about through procfs, not
the caller of lookup.
fixes 'ls -l /proc/*/file' panic, which would occur when trying to
lookup "file" for a kernel thread, which doesn't have p->p_textvp.
- LOCKPARENT is no longer relevant for lookup(), relookup() or VOP_LOOKUP().
these now always return the parent vnode locked. namei() works as before.
lookup() and various other paths no longer acquire vnode locks in the
wrong order via vrele(). fixes PR 32535.
as a nice side effect, path lookup is also up to 25% faster.
- the above allows us to get rid of PDIRUNLOCK.
- also get rid of WANTPARENT (just use LOCKPARENT and unlock it).
- remove an assumption in layer_node_find() that all file systems implement
a recursive VOP_LOCK() (unionfs doesn't).
- require that all file systems supply vfs_vptofh and vfs_fhtovp routines.
fill in eopnotsupp() for file systems that don't support being exported
and remove the checks for NULL. (layerfs calls these without checking.)
- in union_lookup1(), don't change refcounts in the ISDOTDOT case, just
adjust which vnode is locked. fixes PR 33374.
- apply fixes for ufs_rename() from ufs_vnops.c rev. 1.61 to ext2fs_rename().
First, remove process_checkioperm() calls from MD code. Similar checks
using kauth(9) routines (on the process scope, using appropriate action)
are done in the callers.
Add secmodel back-end to handle each subsystem.
- struct timeval time is gone
time.tv_sec -> time_second
- struct timeval mono_time is gone
mono_time.tv_sec -> time_uptime
- access to time via
{get,}{micro,nano,bin}time()
get* versions are fast but less precise
- support NTP nanokernel implementation (NTP API 4)

directly to the directory containing the pid instead of pointing to
/proc/curproc, because some programs rely on calling readlink on /proc/self
to get the pid.
link points to the process's current working directory, and the root
link points to the process's root directory. What else would you
expect?
For directories that are out of reach (caller is in a chroot, target
process is in a different chroot, etc), the links point to "/"
instead.
current directory in curproc. Fix from Pedro Martelletto:
We cannot call vgone() from procfs_inactive() if we are coming from
vclean(). that's what's probably causing the deadlock.
kernel and ran for a day or so. There are still some caddr_t types in
the arguments of some calls, I will do those separately (later) as
they touch a lot more of the system.

to have KFS or PFS differentiators. Further I have wrapped the enum in
procfs in "#ifdef _KERNEL" as it is done in kernfs.
To see the discussion go to http://mail-index.NetBSD.org/tech-kern/2003/09/
and look for "Mismatched enums in include files" in the list.
