This becomes important later when you try remove dev_t. Oops, ignore the patches to devfs, I didn't mean to include them. they are not yet functional. they will bypass the devsw tables entirely when I remove the deliberate mistakes. :-) I have not yet initialised the dump and psize entries in wd, sd, etc. I do not include patches I have been working on to make all users of bdevs look at the cdevs yet. that works with devfs as the major Anumbers can become the same. but it's not generally applicable without it. (I gather you will be 'bouncing' bdevs through the bdevsw to the cdevsw entry to start with?) > > julian > > On Thu, 25 Jun 1998, Poul-Henning Kamp wrote: > > > phk 1998/06/25 04:28:09 PDT > > > > Modified files: > > sys/i386/isa wcd.c > > sys/kern kern_conf.c kern_lkm.c > > sys/sys conf.h > > sys/vm vm_swap.c > > Log: > > Remove bdevsw_add(), change the only two users to use bdevsw_add_generic(). > > Extend cdevsw to be superset of bdevsw. > > Remove non-functional bdev lkm support. > > Teach wcd what the open() args mean. > > > > Revision Changes Path > > 1.55 +27 -53 src/sys/i386/isa/wcd.c > > 1.25 +7 -2 src/sys/kern/kern_conf.c > > 1.50 +1 -18 src/sys/kern/kern_lkm.c > > 1.42 +6 -2 src/sys/sys/conf.h > > 1.54 +9 -13 src/sys/vm/vm_swap.c > > > > To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe cvs-all" in the body of the message
