* Eliminate ramdisk.c and ramdisk.h now that they're unused.matthew2011-06-231-633/+0

* Drop kernel support for the useless DIOCWLABEL ioctl and prune a lotmatthew2011-06-051-8/+1

* Get rid of the wlabel argument to bounds_check_with_label(). It'smatthew2011-06-031-2/+2
| | | | | | | | | never done anything in OpenBSD and just clutters disk drivers with silly flag handling. More cleanup to follow. ok deraadt@, millert@; no objections krw@
* Change a few of the more common disk drivers (sd, cd, wd, rd, and vnd)matthew2011-05-311-2/+2
| | | | | | | | | | | | | | | | | | | to return EBUSY if the user tries to modify an open partition's offset or size. Only sadness can result if a user tries this, and rejecting it prevents a race between sdstart() and sdstrategy(). Curiously, there was already code in the kernel and in disklabel(8) to detect/handle this, but it was effectively disabled because the disk drivers always used something like "/* sc->sc_dk.dk_openmask */ 0", and this commented out code has existed since even r1.1 in NetBSD. I had no problems building a release and messing around with disklabel(8) for a bit with this diff. Canarying the more common MI disk drivers until we gain confidence that there aren't any regressions, then we can switch the remaining drivers. "I am surprised you got me convinced that this stuff is safe" deraadt@ ok krw@

* Don't bypass partition bounds check for RAW_PART. We now guarantee thatkrw2008-06-151-5/+3
| | | | | | | | | | | RAW_PART will always be 0 -> disksize, so the bounds check will always pass for i/o's to valid addresses. Now the i/o will be properly truncated if it goes past the end of the device. This prevents various adverse impacts of issuing i/o's for data past the end of the device. Repeatedly requested by todd@. ok weingart@ deraadt@

| | | | | | | | | | | 'fakerootdev' hackery. This allows us to bring back miod@'s r1.70 subr_disk.c change to avoid the GENERIC dance when rootdev has been initialized. This in turn re-enables raidframe root devices. Add a nice panic if rootdev can't be initialized, displaying the name of the device that didn't work rather than just blowing up by de-referencing NULL. ok deraadt@

| | | | | | | | | | setting RAW_PART's p_size to d_secperunit * (d_secsize / DEV_BSIZE) is a waste of a few ops. And p_size should be in sectors anyway. Just set RAW_PART's p_size to d_secperunit to make usage consistant across the tree. Should be a no-op.
