VOP_PUTPAGES() was never triggered resulting in far too much data in the UBC
that needed to be written out. This could result in instability on small
memory machines.
A type specifier of the form

without an enumerator list shall only appear after the type it
specifies is complete.
which means that we cannot pass an "enum vtype" argument to
kauth_access_action() without fully specifying the type first.
Unfortunately there is a complicated include file loop which
makes that difficult, so convert this minimal function into a
macro (and capitalize it).

PR kern/46282 (6.0_BETA crash: msdosfs_bmap -> pcbmap -> bread -> bio_doread)
- Implement NGONE to fix caching issue described in PR kern/25070.
Mostly taken from FreeBSD r125637.
- Revert revision 1.70 of smbfs_vnops.c to fix setattr to opened
direcotry. In case of SMB_CAP_NT_SMBS, NOPEN is set after
smbfs_smb_ntcreatex() call. If NOPEN is set in front, it will
immediately return by condition at do_open label.
- In smbfs_close(), call smbfs_smb_close() and drop NOPEN bit in
the case of direcotry. Otherwise smbfs_rmdir() fails when the
directory was opened.
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.
- 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.
Fixes a side issue mentioned in PR kern/46990.
I left this commented to preserve the old behaviour of tmpfs_rename,
but it is obviously broken to omit the cache purge, and I'm surprised
nobody had encountered any problems with it until now.
tmpfs_vnode_get drops all locks except possibly the reclaiming bit
lock to keep the tmpfs node from being reclaimed while we're still
interested in it. Consequently, it does not keep the directory's
existence invariant, so we must check that after tmpfs_vnode_get.
Fixes PR kern/46990. Tested by Wolfgang Stukenbrock.
