* Remove all traces of Julians DEVFS (incl from kern/subr_diskslice.c)Poul-Henning Kamp2000-08-201-1297/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove old DEVFS support fields from dev_t. Make uid, gid & mode members of dev_t and set them in make_dev(). Use correct uid, gid & mode in make_dev in disk minilayer. Add support for registering alias names for a dev_t using the new function make_dev_alias(). These will show up as symlinks in DEVFS. Use makedev() rather than make_dev() for MFSs magic devices to prevent DEVFS from noticing this abuse. Add a field for DEVFS inode number in dev_t. Add new DEVFS in fs/devfs. Add devfs cloning to: disk minilayer (ie: ad(4), sd(4), cd(4) etc etc) md(4), tun(4), bpf(4), fd(4) If DEVFS add -d flag to /sbin/inits args to make it mount devfs.

* Simplify the handling of VCHR and VBLK vnodes using the new dev_t:Poul-Henning Kamp1999-08-261-15/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make the alias list a SLIST. Drop the "fast recycling" optimization of vnodes (including the returning of a prexisting but stale vnode from checkalias). It doesn't buy us anything now that we don't hardlimit vnodes anymore. Rename checkalias2() and checkalias() to addalias() and addaliasu() - which takes dev_t and udev_t arg respectively. Make the revoke syscalls use vcount() instead of VALIASED. Remove VALIASED flag, we don't need it now and it is faster to traverse the much shorter lists than to maintain the flag. vfs_mountedon() can check the dev_t directly, all the vnodes point to the same one. Print the devicename in specfs/vprint(). Remove a couple of stale LFS vnode flags. Remove unimplemented/unused LK_DRAINED; Notes: svn path=/head/; revision=50405
* Make a place to store the devfs hook for the block device, as the sameJulian Elischer1999-08-251-3/+2
| | | | | | | specinfo is used to identify both raw and block version sof a device. Notes: svn path=/head/; revision=50376
* Make DEVFS use PHK's specinfo struct as the source of dev_t and devsw.Julian Elischer1999-08-251-19/+16
| | | | | | | | | | | In lookup() however it's the other way around as we need to supply the dev_t for the vnode, so devfs still has a copy of it stashed away. Sourcing it from the vnode in the vnops however is useful as it makes a lot of the code almost the same as that in specfs. Notes: svn path=/head/; revision=50334
* Devfs now adds itself to the hook that PHK supplies.Julian Elischer1999-08-241-1/+21

* DEVFS completely bypasses the cdevsw and bdevsw tables now.Julian Elischer1998-07-051-3/+3
| | | | | | | | | | | Each devfs node has (and has had fro a while) a pointer directly to the correct cdefsw entry so just use it instead of doing the lookup. There are several other places in the kernel that still use the tables however, so they can't go away yet.. Notes: svn path=/head/; revision=37407
* There is no such thing any more as "struct bdevsw".Julian Elischer1998-07-041-3/+3
| | | | | | | | | | | | | | | | | | | | | There is only cdevsw (which should be renamed in a later edit to deventry or something). cdevsw contains the union of what were in both bdevsw an cdevsw entries. The bdevsw[] table stiff exists and is a second pointer to the cdevsw entry of the device. it's major is in d_bmaj rather than d_maj. some cleanup still to happen (e.g. dsopen now gets two pointers to the same cdevsw struct instead of one to a bdevsw and one to a cdevsw). rawread()/rawwrite() went away as part of this though it's not strictly the same patch, just that it involves all the same lines in the drivers. cdroms no longer have write() entries (they did have rawwrite (?)). tapes no longer have support for bdev operations.

* Add changes and code to implement a functional DEVFS.Julian Elischer1998-04-191-40/+120
| | | | | | | | | | | | | | | | | | | | | | | | This code will be turned on with the TWO options DEVFS and SLICE. (see LINT) Two labels PRE_DEVFS_SLICE and POST_DEVFS_SLICE will deliniate these changes. /dev will be automatically mounted by init (thanks phk) on bootup. See /sys/dev/slice/slice.4 for more info. All code should act the same without these options enabled. Mike Smith, Poul Henning Kamp, Soeren, and a few dozen others This code does not support the following: bad144 handling. Persistance. (My head is still hurting from the last time we discussed this) ATAPI flopies are not handled by the SLICE code yet. When this code is running, all major numbers are arbitrary and COULD be dynamically assigned. (this is not done, for POLA only) Minor numbers for disk slices ARE arbitray and dynamically assigned.

| | | | | | | | | | | | | | | They are atomic, but return in essence what is in the "time" variable. gettime() is now a macro front for getmicrotime(). Various patches to use the two new functions instead of the various hacks used in their absence. Some puntuation and grammer patches from Bruce. A couple of XXX comments.
