Repply this change with a couple of bugs fixed:

- Do away with separate pool_cache for some kernel objects that have no special
  requirements and use the general purpose allocator instead. On one of my
  test systems this makes for a small (~1%) but repeatable reduction in system
  time during builds presumably because it decreases the kernel's cache /
  memory bandwidth footprint a little.
- vfs_lockf: cache a pointer to the uidinfo and put mutex in the data segment.

Now remove cn_consume from struct componentname.

This change requires a kernel bump.

Note though that I'm not going to version the VOP_LOOKUP args
structure (or any other args structure) as code that doesn't touch
cn_consume doesn't need attention and code that does will fail on it
without further intervention.

Pull up following revision(s) (requested by dholland in ticket #1685):

	sys/sys/namei.src: revision 1.59	(via patch)
	sys/kern/vfs_vnops.c: revision 1.215
	sys/kern/vfs_lookup.c: revision 1.226

Add a new namei flag NONEXCLHACK for open with O_CREAT and not O_EXCL.
This case needs to be distinguished from the other CREATE operations
because it is supposed to successfully return (and open) the target if
it exists. In the case where that target is the root, or a mount
point, such that there's no parent dir, "real" CREATE operations fail,
but O_CREAT without O_EXCL needs to succeed.

So (a) add the flag, (b) test for it in namei in the situation
described above, (c) set it in open under the appropriate
circumstances, and (d) because this can result in namei returning
ni_dvp of NULL, cope with that case.

Should get into -9 and maybe even -8, because it was prompted by
issues with 3rd-party code. The use of a flag (vs. adding an
additional nameiop, which would be more appropriate) was deliberate to
make the patch small and noninvasive.

A couple of small changes to lookup that cut 5-10% system time from
"build.sh release" on my test system:

- Crossing mount points during lookup is slow because the set up for, and
  act of doing VFS_ROOT() is quite involved.  Use the name cache to help
  with this.  Cache an "impossible" zero-length name with covered vnodes,
  that points to the root of the file system mounted there.  Use it to cross
  mounts.  When cache_purge() is called on either of the vnodes involved the
  cache entry will disappear.  All of the needed calls for that are already
  in place (vnode reclaim, unmount, etc).

- In lookup_fastforward(), if the the last component has been found and the
  parent directory (searchdir) is not going to be returned, then don't get a
  reference to it.

Merge the remaining changes from the ad-namecache branch, affecting namei()
and getcwd():

- push vnode locking back as far as possible.
- do most lookups directly in the namecache, avoiding vnode locks & refs.
- don't block new refs to vnodes across VOP_INACTIVE().
- get shared locks for VOP_LOOKUP() if the file system supports it.
- correct lock types for VOP_ACCESS() / VOP_GETATTR() in a few places.

Possible future enhancements:

- make the lookups lockless.
- support dotdot lookups by being lockless and inferring absence of chroot.
- maybe make it work for layered file systems.
- avoid vnode references at the root & cwd.

- Add a LOCKSHARED flag to namei (matching FreeBSD) indicating that we want
  the leaf locked with LK_SHARED.

- Add an IMNT_SHRLOOKUP flag to struct mount indicating that the file
  system can do VOP_LOOKUP() with an shared lock.  If it encounters
  something tricky, VOP_LOOKUP() is free to return ENOLCK and namei() will
  retry the lookup with an exclusive lock.  If the file system has this flag
  set, namei() will try with shared locks for all of the "read only"
  lookups, i.e. nameiop=LOOKUP or !ISLASTCN.

- vfs_getcwd: only take vnode locks when really needed, take shared locks if
  possible, and where the namecache has identify info for the directories,
  do it all in the namecache.

- vfs_lookup: when crossing mountpoints take only a shared lock on the
  covered vnode; don't need anything else.

vfs_lookup:

- Do the easy component name lookups directly in the namecache without
  taking vnode locks nor vnode references (between the start and the leaf /
  parent), which seems to largely solve the lock contention problem with
  namei().  It needs support from the file system, which has to tell the
  name cache about directory permissions (only ffs and tmpfs tried so far),
  and I'm not sure how or if it can work with layered file systems yet.
  Work in progress.

vfs_cache:

- Make the rbtree operations more efficient: inline the lookup, and key on a
  64-bit hash value (32 bits plus 16 bits length) rather than names.

- Take namecache stuff out of vnode_impl, and take the rwlocks, and put them
  all together an an nchnode struct which is mapped 1:1: with vnodes.  Saves
  memory and nicer cache profile.

- Add a routine to help vfs_lookup do its easy component name lookups.

- Report some more stats.

- Tidy up the file a bit.

namecache:

This is working better than expected.  It seems to cut system time for
build.sh by ~10% on my test machine and joerg@ is seeing better results with
pbulk.  Improve it a bit more without changing the basic idea:

- Split cache_list_lock into a per-vnode rwlock for reverse lookup, and a
  lightly contended global lock on LRU state (cache_lru_lock),

- For LRU replacement, imitate the VM system's page replacement algorithm.
  This eliminates the writebacks to struct namecache (to track time of last
  hit).

- Dynamically allocate the per-directory lock, preparing the way for having
  a "struct nchdir" or similar which could contain stuff like different
  structures for lookup, cached info to do the equivalent of VOP_ACCESS() in
  cache, and so on.

namecache changes:

- Delete the per-entry lock, and borrow the associated vnode's v_interlock
  instead.  We need to acquire it during lookup anyway.  We can revisit this
  in the future but for now it's a stepping stone, and works within the
  quite limited context of what we have (BSD namecache/lookup design).

- Implement an idea that Mateusz Guzik (mjg@FreeBSD.org) gave me.  In
  cache_reclaim(), we don't need to lock out all of the CPUs to garbage
  collect entries.  All we need to do is observe their locks unheld at least
  once: then we know they are not in the critical section, and no longer
  have visibility of the entries about to be garbage collected.

- The above makes it safe for sysctl to take only namecache_lock to get stats,
  and we can remove all the crap dealing with per-CPU locks.

- For lockstat, make namecache_lock a static now we have __cacheline_aligned.

- Avoid false sharing - don't write back to nc_hittime unless it has changed.
  Put a a comment in place explaining this.  Pretty sure this was there in
  2008/2009 but someone removed it (understandably, the code looks weird).

- Use a mutex to protect the garbage collection queue instead of atomics, and
  adjust the low water mark up so that cache_reclaim() isn't doing so much
  work at once.

Excise struct componentname from the namecache.

This uglifies the interface, because several operations need to be
passed the namei flags and cache_lookup also needs for the time being
to be passed cnp->cn_nameiop. Nonetheless, it's a net benefit.

The glop should be able to go away eventually but requires structural
cleanup elsewhere first.

This change requires a kernel bump.

Disentangle the namecache from the internals of namei.

 - Move the namecache's hash computation to inside the namecache code,
instead of being spread out all over the place. Remove cn_hash from
struct componentname and delete all uses of it.

 - It is no longer necessary (if it ever was) for cache_lookup and
cache_lookup_raw to clear MAKEENTRY from cnp->cn_flags for the cases
that cache_enter already checks for.

 - Rearrange the interface of cache_lookup (and cache_lookup_raw) to
make it somewhat simpler, to exclude certain nonexistent error
conditions, and (most importantly) to make it not require write access
to cnp->cn_flags.

This change requires a kernel bump.

Add namei-level support for openat() and friends. The way you do it is

Right now the implementation is vile and unspeakable to avoid changing

will rectify the mess and bump the kernel once things are working.

Check all call sites to make sure that SAVESTART wasn't set while
calling relookup(); if it was, adjust the refcount behavior. Remove
related references to SAVESTART.

The only code that was reaching the extra ref was msdosfs_rename,
where the refcount behavior was already fairly broken and/or gross;
repair it.

Add a dummy 4th argument to relookup to make sure code that hasn't
been inspected won't compile. (This will go away next time the
relookup semantics change, which they will.)

Add an INRELOOKUP namei flag. Sigh. (We don't need more namei flags.)

However, because of a protocol deficiency puffs relies on being able
to keep track of VOP_LOOKUP calls by inspecting their contents, and
this at least allows it to use something vaguely principled instead of
making wild guesses based on whether SAVESTART is set.

Update libp2k to use INRELOOKUP instead of SAVESTART.

Introduce struct pathbuf. This is an abstraction to hold a pathname
and the metadata required to interpret it. Callers of namei must now
create a pathbuf and pass it to NDINIT (instead of a string and a
uio_seg), then destroy the pathbuf after the namei session is
complete.

Update all namei call sites accordingly. Add a pathbuf(9) man page and
update namei(9).

The pathbuf interface also now appears in a couple of related
additional places that were passing string/uio_seg pairs that were
later fed into NDINIT. Update other call sites accordingly.

Define namei flag INRENAME and set it if a lookup operation is part
of rename.  This helps with building better asserts for rename in
the DELETE lookup ... the RENAME lookup is quite obviously a part
of rename.

Move a big wodge of symlink-following code from nfsd to inside
lookup_for_nfsd(). This code is, or at least should be, the same as
the regular symlink-following code plus an extra flag nfsd needs.

The two lots of code can/will be merged in the future.

Rename lookup() to lookup_for_nfsd(), to make it clear just whose
private backdoor entry point this is.

Also, clone the lookup_for_nfsd() entry point as
lookup_for_nfsd_index(), for use by a different call site in nfsd that
does different unclean things with nameidata.

Add namei_simple_kernel and namei_simple_user. These provide the common
case functionality of namei in a simple package with only a couple flags.

A substantial majority of the namei call sites in the kernel can use
this interface; this will isolate those areas from the changes arising
as the internals of namei are fumigated.
