* Suser() simplification:Poul-Henning Kamp1999-04-271-2/+2
| | | | | | | | | | | | | | | | | | | | | | 1: s/suser/suser_xxx/ 2: Add new function: suser(struct proc *), prototyped in <sys/proc.h>. 3: s/suser_xxx(\([a-zA-Z0-9_]*\)->p_ucred, \&\1->p_acflag)/suser(\1)/ The remaining suser_xxx() calls will be scrutinized and dealt with later. There may be some unneeded #include <sys/cred.h>, but they are left as an exercise for Bruce. More changes to the suser() API will come along with the "jail" code.

| | | | | | | | | | | | | | The old VN device broke in -4.x when the definition of B_PAGING changed. This patch fixes this plus implements additional capabilities. The new VN device can be backed by a file ( as per normal ), or it can be directly backed by swap. Due to dependencies in VM include files (on opt_xxx options) the new vn device cannot be a module yet. This will be fixed in a later commit.

* Added a flags arg to dsopen() and updated drivers. The DSO_ONESLICEBruce Evans1998-07-301-3/+3
| | | | | | | | | | | | | | and DSO_NOLABELS flags prevent searching for slices and labels respectively. Current drivers don't set these flags. When DSO_NOLABELS is set, the in-core label for the whole disk is cloned to create an in-core label for each slice. This gives the correct result (a good in-core label for the compatibility slice) if DSO_ONESLICE is set or only one slice is found, but usually gives broken labels otherwise, so DSO_ONESLICE should be set if DSO_NOLABELS is set.

* There is no such thing any more as "struct bdevsw".Julian Elischer1998-07-041-7/+25
| | | | | | | | | | | | | | | | | | | | | 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 Elischer1998-04-191-35/+314
| | | | | | | | | | | | | | | | | | | | | | | | 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.

* Clustered read and write are switched at mount-option level.KATO Takenori1997-09-271-3/+3
| | | | | | | | | | | | | | | | | | | 1. Clustered I/O is switched by the MNT_NOCLUSTERR and MNT_NOCLUSTERW bits of the mnt_flag. The sysctl variables, vfs.foo.doclusterread and vfs.foo.doclusterwrite are deleted. Only mount option can control clustered I/O from userland. 2. When foofs_mount mounts block device, foofs_mount checks D_CLUSTERR and D_CLUSTERW bits of the d_flags member in the block device switch table. If D_NOCLUSTERR / D_NOCLUSTERW are set, MNT_NOCLUSTERR / MNT_NOCLUSTERW bits will be set. In this case, MNT_NOCLUSTERR and MNT_NOCLUSTERW cannot be cleared from userland. 3. Vnode driver disables both clustered read and write. 4. Union filesystem disables clutered write. Reviewed by: bde Notes: svn path=/head/; revision=29888

I've also added DEVFS support for nearly every device in the system, however many of the devices have 'incorrect' names under DEVFS because I couldn't quickly work out the correct naming conventions. (but devfs won't be coming on line for a month or so anyhow so that doesn't matter) If you "OWN" a device which would normally have an entry in /dev then search for the devfs_add_devsw() entries and munge to make them right.. check out similar devices to see what I might have done in them in you can't see what's going on.. for a laugh compare conf.c conf.h defore and after... :) I have not doen DEVFS entries for any DISKSLICE devices yet as that will be a much more complicated job..
