* Device megapatch 5/6:phk2004-02-214-5/+5
| | | | | | | | | | | | Remove the unused second argument from udev2dev(). Convert all remaining users of makedev() to use udev2dev(). The semantic difference is that udev2dev() will only locate a pre-existing dev_t, it will not line makedev() create a new one. Apart from the tiny well controlled windown in D_PSEUDO drivers, there should no longer be any "anonymous" dev_t's in the system now, only dev_t's created with make_dev() and make_dev_alias()
* Device megapatch 4/6:phk2004-02-2179-37/+161
| | | | | | | | Introduce d_version field in struct cdevsw, this must always be initialized to D_VERSION. Flip sense of D_NOGIANT flag to D_NEEDGIANT, this involves removing four D_NOGIANT flags and adding 145 D_NEEDGIANT flags.
* Device megapatch 3/6:phk2004-02-2117-46/+2
| | | | | | | | | | | | Add missing D_TTY flags to various drivers. Complete asserts that dev_t's passed to ttyread(), ttywrite(), ttypoll() and ttykqwrite() have (d_flags & D_TTY) and a struct tty pointer. Make ttyread(), ttywrite(), ttypoll() and ttykqwrite() the default cdevsw methods for D_TTY drivers and remove the explicit initializations in various drivers cdevsw structures.
* Device megapatch 2/6:phk2004-02-212-102/+97
| | | | | | | | | | | | | | | | | | | | | | | | | | This commit adds a couple of functions for pseudodrivers to use for implementing cloning in a manner we will be able to lock down (shortly). Basically what happens is that pseudo drivers get a way to ask for "give me the dev_t with this unit number" or alternatively "give me a dev_t with the lowest guaranteed free unit number" (there is unfortunately a lot of non-POLA in the exact numeric value of this number, just live with it for now) Managing the unit number space this way removes the need to use rman(9) to do so in the drivers this greatly simplifies the code in the drivers because even using rman(9) they still needed to manage their dev_t's anyway. I have taken the if_tun, if_tap, snp and nmdm drivers through the mill, partly because they (ab)used makedev(), but mostly because together they represent three different problems for device-cloning: if_tun and snp is the plain case: just give me a device. if_tap has two kinds of devices, with a flag for device type. nmdm has paired devices (ala pty) can you can clone either of them.

* Change the disk(9) API in order to make device removal more robust.phk2004-02-1821-171/+206
| | | | | | | | | | | | | | | | | | | | | | | | Previously the "struct disk" were owned by the device driver and this gave us problems when the device disappared and the users of that device were not immediately disappearing. Now the struct disk is allocate with a new call, disk_alloc() and owned by geom_disk and just abandonned by the device driver when disk_create() is called. Unfortunately, this results in a ton of "s/\./->/" changes to device drivers. Since I'm doing the sweep anyway, a couple of other API improvements have been carried out at the same time: The Giant awareness flag has been flipped from DISKFLAG_NOGIANT to DISKFLAG_NEEDSGIANT A version number have been added to disk_create() so that we can detect, report and ignore binary drivers with old ABI in the future. Manual page update to follow shortly.
