* Expand the example descriptions, fix mdoc-bugs in
"(-a and -t vnode are implied)"
and reuse it near the cd9660 example.
* Spell 'backing store' as two words.


# 284096f7 09-Nov-2007 Giorgos Keramidas <keramida@FreeBSD.org>

Instead of hardcoding md10 as the device node in the cd9660 example,
use a trick submitted by Ruslan.

Update the description of -l to reflect reality. After mdconfig.c
1.25, -l without -u only lists the names, so specifying -u does more
than just limit the output to one device.

Fix a long-standing deadlock issue with vnode backed md(4) devices:

On vnode backed md(4) devices over a certain, currently undetermined
size relative to the buffer cache our "lemming-syncer" can provoke
a buffer starvation which puts the md thread to sleep on wdrain.

This generally tends to grind the entire system to a stop because the
event that is supposed to wake up the thread will not happen until a fair
bit of the piled up I/O requests in the system finish, and since a lot
of those are on a md(4) vnode backed device which is currently waiting
on wdrain until a fair amount of the piled up ... you get the picture.

The cure is to issue all VOP_WRITES on the vnode backing the device
with IO_SYNC.

In addition to more closely emulating a real disk device with a
non-lying write-cache, this makes the writes exempt from rate-limited
(there to avoid starving the buffer cache) and consequently prevents
the deadlock.

Unfortunately performance takes a hit.

Add "async" option to give people who know what they are doing the
old behaviour.
