so that mmap()ped regions remain accessible even when the file descriptor
is closed
g/c smbnode's n_opencount, and have single NOPEN flag instead
fixes PR kern/24516 by Lloyd Parkes
change obtained from FreeBSD, with only minor adjustments
* Remove the "lwp *" argument that was added to vget(). Turns out
that nothing actually used it!
* Remove the "lwp *" arguments that were added to VFS_ROOT(), VFS_VGET(),
and VFS_FHTOVP(); all they did was pass it to vget() (which, as noted
above, didn't use it).
* Remove all of the "lwp *" arguments to internal functions that were added
just to appease the above.
be inserted into ktrace records. The general change has been to replace
"struct proc *" with "struct lwp *" in various function prototypes, pass
the lwp through and use l_proc to get the process pointer when needed.
Bump the kernel rev up to 1.6V

bump the timeout to 5s; eventually we'd want to do some heuristics similar
to NFS, i.e. make the attribute cache timeout longer for files nor recently
changed
former smbfs_hash() may have accessed memory past buffer (ouch!), and accessed
memory in alignment-unsafe way
as an added bonus, hash32_strn() appears to have better distribution
* use LK_RETRY for the vget()
* turn the check for dead parent vnode to #ifdef DIAGNOSTIC panic
* reformat the hash walk code a little, and only assign vp if entries match
* add some comments
make smbfs_name_{alloc|free} inline
turn some checks for smbfs code errors to KASSERT()s

also initialize n_size in smbfs_node_alloc()
g/c write-only variable in smbfs_nget()
#if 0 smbfs_hashprint(), and mark it static
do NOT reinit vp->v_lock - getnewvnode() did it for us
smbfs_reclaim(): unconditionaly do LIST_REMOVE(), and de-obfuscate parent
directory vrele() call
malloc types into a structure, a pointer to which is passed around,
instead of an int constant. Allow the limit to be adjusted when the
malloc type is defined, or with a function call, as suggested by
Jonathan Stone.
