The writer daemon, if it does not need to flush the whole filesystem,
now only writes the vnodes for which the pagedaemon has requested pageouts
(although it does not pay attention to the page ranges the pagedaemon
supplies).
by Michel Oey, in which an aged LFS writes up to an extra Ifile block for
every file created; and paves the way for the truncation of the Ifile when
many files are deleted.
* Correct (weak) segment lock assertions in lfs_fragextend and lfs_putpages.
* Keep IN_MODIFIED set if we run out of avail in lfs_putpages.
* Don't try to (re)write buffers on a VBLK vnode; fixes a panic I found
while running with an LFS root.
* Raise priority of LFCNSEGWAIT to PVFS; PUSER is way too low for
something the pagedaemon is relying on.
gpioow(4), attaching a bit-banging driver via a GPIO pin. Also,
owtemp(4) which supports some of the 1-Wire temperature sensors, including
the DS18b20 and DS1920 - temperatures are returned via the envsys(4)
framework.
Original drivers by Alexander Yurchenko (grange@openbsd), with envsys(4)
support and a fix to the 1-wire search algorithm (for discovering
devices on the bus) by me.
As discussed on tech-kern earlier this week.

In addition, code from NetBSD/alpha NetBSD/sparc64,
NetBSD/i386 and NetBSD/amd64 were used as templates,
along with my own additions.

- dkwedge_del(): Don't compute a minor number based on partitions, because
wedges don't have partitions. Just provide the unit number to vdevgone().
- dkopen(): Make sure we release all of the locks we've acquired should
opening the parent device fail.
