devices.txt inconsistency

devices.txt inconsistency

[Ari Pollak]

This has not been fixed for at least a year that i can remember - in
Documentation/devices.txt, it says /dev/js* should be char-major-15*,
but in Documentation/joystick.txt it says it should be char-major-13.
I'm assuming joystick.txt is the correct one, and devices.txt should be
updated to reflect this.. before 2.4.0 would be nice.

devices.txt does need some updating. It still lists char-major-13 as
the PC Speaker, but 13 appears to be the major for new input driver,
and the joystick driver is now a minor off the that.  Are there now
two Joystick drivers, or can char-major-15 be obsoleted/deleted?

I think there are two; at least, the number will remain reserved for a
long time.

The current devices.txt is available at:

   http://www.lanana.org/docs/device-list/devices.txt

I don't have the details for /dev/input/* in there; I need to still
make that update.

How's this?  Should char-major-15 be obsoleted, deleted or just left
in for now?

Re: devices.txt inconsistency

[Douglas Gilbert]

While on this subject, the description of raw devices
(char 162) in lk 2.4 is not consistent with current 
usage.

devices.txt contains this:
162 char        Raw block device interface
                  0 = /dev/raw          Raw I/O control device
                  1 = /dev/raw1         First raw I/O device
                  2 = /dev/raw2         Second raw I/O device
                    ...

but something like this would be more accurate:
162 char        Raw block device interface
                  0 = /dev/rawctl       Raw I/O control device
                  1 = /dev/raw/raw1     First raw I/O device
                  2 = /dev/raw/raw2     Second raw I/O device
                    ...

The raw(8) command supplied in RH 6.2 and 7.0 assumes the
latter structure. I have already alerted sct and this 
change may be coming through in one of his patches.

The latter is actually better, so I certainly don't mind.  sct, should I
change it?
