along with the rest of FILE. This eliminates the need for a
separate allocation of flockfile state as well as eliminating
the mutex/lock used to serialize its allocation.
for selecting unit). Instead, use the resource hints mechanism.
One unfortunate situation here is that there is no resource_quad_value
function- which is what I needed for WWN boot time replacement. Worse-
you can't store the hint as just plain
hint.isp.0.nodewwn="0x50000000aaaa0001"
because this gets interpreted as an int- incorrectly because it can't
be converted to an int. I can't even get this as a string. To work
around this particular case for nodewwn && portwwn setting, this
rather grotesque form will be used:
hint.isp.0.nodewwn="w50000000aaaa0001"
hint.isp.0.portwwn="w50000000aaaa0002"
At the same time, if we have no hinted WWN, set the default WWN (which, btw,
gets overridden if the card has valid NVRAM, which is usual) to
0x400000007F000009ull (which translates to NAA == IPv4, 127.0.0.9).
Eliminate more printf's and replace them either with device_printf or

Eliminate isp_unit references- we no longer have an isp_unit- we now
have an isp_dev that device_get_unit can work with.
`rootvnode' pointer, but vfs_syscalls.c's checkdirs() assumed that
it did. This bug reliably caused a panic at reboot time if any
filesystem had been mounted directly over /.
The checkdirs() function is called at mount time to find any process
fd_cdir or fd_rdir pointers referencing the covered mountpoint
vnode. It transfers these to point at the root of the new filesystem.
However, this process was not reversed at unmount time, so processes
with a cwd/root at a mount point would unexpectedly lose their
cwd/root following a mount-unmount cycle at that mountpoint.
This change should fix both of the above issues. Start_init() now
holds an extra vnode reference corresponding to `rootvnode', and
dounmount() releases this reference when the root filesystem is
unmounted just before reboot. Dounmount() now undoes the actions
taken by checkdirs() at mount time; any process cdir/rdir pointers
that reference the root vnode of the unmounted filesystem are
transferred to the now-uncovered vnode.

1) Fix a bug where the recursion on prefixes where if recusrion failed
then the next attempt started too far along the string.
2) Up some internal limits that we were about to hit off.
3) Change the constness and signedness of some things and complete missing

4) Remove the readerror function 'cos it could print out the wrong

5) Use sizeof when passing buffers to fgets.

a regular basis. Adjust our linux emulation to conform. This will
cause more dirty pages to be left for the pagedaemon to deal with,
but our new low-memory handling code can deal with it. The linux
way appears to be a trend, and we may very well make MAP_NOSYNC the
default for FreeBSD as well (once we have reasonable sequential
write-behind heuristics for random faults).

make sure that PG_NOSYNC is properly set. Previously we only set it
for a write-fault, but this can occur on a read-fault too.

Pipeline operations turned off for all READs (no big loss since reads are
usually synchronous) and for NFS writes, and left on for the default bwrite().

update native priority, it is diffcult to get right and likely
to end up horribly wrong. Use an honestly wrong fixed value
that seems to work; PUSER for user threads, and the interrupt
priority for ithreads. Set it once when the process is created
and forget about it.

1) blackholes.mail-abuse.org is the same as FEATURE(dnsbl), so specifying
it in the "Other DNS based black hole lists" section leads to confusion of
specifying it twice.
2) Formatting issues. If error diagnostic not enclosed in double quotes,
varius visual artefacts appearse like 1) no space after ; and 2) redundant
space after ? (in CGI request), so I add quotes where needed.
3) FEATURE(dnsbl) directly use error code 550 by default, so I made other
dnsbl variants use the same error code too.
4) Comment relays.* list as "open relays" list, just "other" word is not
explain enough.
