In sys/mkdev.h, we have:
/*
* SVR3/Pre-EFT device number constants.
*/
#define ONBITSMAJOR 7 /* # of SVR3 major device bits */
#define ONBITSMINOR 8 /* # of SVR3 minor device bits */
#define OMAXMAJ 0x7f /* SVR3 max major value */
#define OMAXMIN 0xff /* SVR3 max major value */
There is also in libc a _makedev() that could in theory be used to use
SVR3 device numbers. But I don't think it is ever called by any code.
Couldn't we just get rid of these defines now? We've long since passed
the point where those values are usable. I suppose if someone had an
svr3 binary mknod, but such a program would be utterly useless since it
couldn't create nodes used by a great many drivers.
Can we nuke 'em?
