7b778b5e61 Make all file-system (MFS, FFS, NFS, LFS, DEVFS) related option new-style.
This introduce an xxxFS_BOOT for each of the rootable filesystems.
(Presently not required, but encouraged to allow a smooth move of option *FS
to opt_dontuse.h later.)

LFS is temporarily disabled, and will be re-enabled tomorrow.

58ffdf1d65 If available, use the device's LOGICAL blocksize as reported by
the "READ_CAPACITY" command, rather than the physical blocksize
reported in the physical geometry code-page.

Also don't print out worrying bogus messages when probing a
device that has no media. There's no point in printing out
something that is unknowable. It just confuses things.

Move the check for valid blocksize out of 'open()' to the subroutine
that actually finds this out, thus probe/attach can also report and
act on the problem.

37b4744c2a Fixed the sector size frobbing in sd_strategy() at least not to
break for the usual sector size.  dscheck() adjusts b_bcount to
handle EOF, so we must scale it and not preserve it.  i/o beyond
the end of partitions has been broken since rev.1.96.

4dec470e39 Remove the call to scsi_start_unit() from sd_open(). It was causing
much grieve to owners of IBM drives when used in conjunction with
tagged command queuing, and didn't serve any purpose at all (since
experiments have proven that it simply didn't work).

Instead, call scsi_start_unit() once in sd_attach(), so in case the
drive has been configured to `remote start', it will spin up there.
(If it has spun down later, it must have been because of administrator
action (scsi(8)) anyway.)

While i was at it, bump the timeout for scsi_start_unit() to 30
seconds.  10 seconds were way too few for most drives.

7a1d27b301 Introduce an advisory exclusive lock on the scsi link structure.
Change sd_open, sd_close and sd_ioctl to use this lock to ensure
serialization of some critical operations, thus avoiding some
race conditions. Ideas picked from NetBSD (ccd and sd devices).
This fixes one of the problems noted in PR kern/3688.

996c772f58 This is the kernel Lite/2 commit. There are some requisite userland
changes, so don't expect to be able to run the kernel as-is (very well)
without the appropriate Lite/2 userland changes.

The system boots and can mount UFS filesystems.

Untested: ext2fs, msdosfs, NFS
Known problems: Incorrect Berkeley ID strings in some files.
		Mount_std mounts will not work until the getfsent
		library routine is changed.

0f49e57b57 Removed `Debugger("no slices")'. It's normal and harmless to have no
slices in sd_open() after a media change when the previous sd_open()
discards the previous slices and then fails.  sd_open() just handles
media changes poorly and fails too often.

7cb29d3394 This update adds the support for != 512 byte sector SCSI devices to
the sd & od drivers. There is also slight changes to fdisk & newfs
in order to comply with different sectorsizes.
Currently sectors of size 512, 1024 & 2048 are supported, the only
restriction beeing in fdisk, which hunts for the sectorsize of
the device.
This is based on patches to od.c and the other system files by
John Gumb & Barry Scott, minor changes and the sd.c patches by
me.
There also exist some patches for the msdos filesys code, but I
havn't been able to test those (yet).

2176b02c56 The sd and od drivers didn't check for negative block numbers (like wd.c
does) before calling dscheck().  dscheck() doesn't appreciate this and
calls Debugger() and returns without setting bp->b_error.

This can happen when there is a casting error and offsets > 2G are
converted to negative off_t's in the disk tools.  (dumpfs used to do this).

c8f2fe8db8 First attempt at creating devfs entries for sliced devices. Doesn't

them go away at the right times.  DEVFS is #undefed at the start so
that this shouldn't cause problems.

87f6c6625d Pass 3 of the great devsw changes
most devsw referenced functions are now static, as they are
in the same file as their devsw structure. I've also added DEVFS
support for nearly every device in the system, however
many of the devices have 'incorrect' names under DEVFS
because I couldn't quickly work out the correct naming conventions.
(but devfs won't be coming on line for a month or so anyhow so that doesn't
matter)

If you "OWN" a device which would normally have an entry in /dev
then search for the devfs_add_devsw() entries and munge to make them right..
check out similar devices to see what I might have done in them in you
can't see what's going on..
for a laugh compare conf.c conf.h defore and after... :)
I have not doen DEVFS entries for any DISKSLICE devices yet as that will be
a much more complicated job.. (pass 5 :)

pass 4 will be to make the devsw tables of type (cdevsw * )
rather than (cdevsw)
seems to work here..
complaints to the usual places.. :)

53ac6efbd8 OK, that's it..
That's EVERY SINGLE driver that has an entry in conf.c..
my next trick will be to define cdevsw[] and bdevsw[]
as empty arrays and remove all those DAMNED defines as well..

Each of these drivers has a SYSINIT linker set entry
that comes in very early.. and asks teh driver to add it's own
entry to the two devsw[] tables.

some slight reworking of the commits from yesterday (added the SYSINIT
stuff and some usually wrong but token DEVFS entries to all these
devices.

BTW does anyone know where the 'ata' entries in conf.c actually reside?
seems we don't actually have a 'ataopen() etc...

If you want to add a new device in conf.c
please  make sure I know
so I can keep it up to date too..

as before, this is all dependent on #if defined(JREMOD)
(and #ifdef DEVFS in parts)
