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)
Convert the remaining sysctl stuff to the new way of doing things.
the devconf stuff is the reason for the large number of files.
Cleaned up some compiler warnings while I were there.
replacing them with TAILQ's as appropriate. The SCSI code is the
first to be changed -- until the changes are complete, both b_act and
b_actf will be in the buf structure. b_actf will eventually be removed.
sometime around 1.51, the check for minphys dissappeared out of
transfers for disks..
we weren't hecking that the adapter could handle a transfer of
the size we were requesting..

this explains the rash of failures I've seen reported recently

function calls. Broken tracking of open partitions gets fixed as a side
effect. Races in sdopen() and sdioctl() become more numerous than before.
Close the device in sdsize(). Media removal could not have worked right
when unused swap devices were held open. There may now be a problem
with used swap devices not being held open.
Fix ancient operator precedence bug in sddump(). It may have been
possible to attempt dumping to unloaded media.
Remove NetBSD ifdefs. We're too different now, and the NetBSD driver was
already too different for them to be relevant.
Remove support for soft write protection. There are no ioctls to set it,
and this driver never set it either. It was used in the wd driver to
disable writing to unlabelled disk, but we want to support writing to
foreign partitions on unlabeled disks.
Clean up some formatting and restore some old-style function headers.

Changes are only effective, if NEW_SCSICONF is defined:
1) Added u_int16 quirks to struct scsi_link for device quirks.
2) Added void *devmodes to struct scsi_link for tape density modes.
3) Modified selectdev() to return first full match (with wildcard).
With this patch all device dependent configuration is done in one place
(scsiconf.c), while there were some specifications in st.c and some
hardware dependent drivers (ie. ncr.c) before.

2) Added ps ddb function from 1.1.5. Cleaned it up a bit and moved into its
own file.
3) Added \r handing in db_printf.
4) Added missing memory usage stats to statclock().
5) Added dummy function to pseudo_set so it will be emitted if there
are no other pseudo declarations.
