* Remove all traces of Julians DEVFS (incl from kern/subr_diskslice.c)Poul-Henning Kamp2000-08-201-313/+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.

The change a couple of days ago to ignore these numbers in statically configured vfsconf structs was slightly premature because the cd9660, cfs, devfs, ext2fs, nfs vfs's still used MOUNT_* instead of the number in their vfsconf struct.

* As described by the submitter:Mike Smith1998-05-061-2/+1
| | | | | | | | | | | | | | | | Reverse the VFS_VRELE patch. Reference counting of vnodes does not need to be done per-fs. I noticed this while fixing vfs layering violations. Doing reference counting in generic code is also the preference cited by John Heidemann in recent discussions with him. The implementation of alternative vnode management per-fs is still a valid requirement for some filesystems but will be revisited sometime later, most likely using a different framework.

* Add changes and code to implement a functional DEVFS.Julian Elischer1998-04-191-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | a complement to all ops that return a vpp, VFS_VRELE. This is initially only for file systems that implement the following ops that do a WILLRELE: vop_create, vop_whiteout, vop_mknod, vop_remove, vop_link, vop_rename, vop_mkdir, vop_rmdir, vop_symlink This is initial DNA that doesn't do anything yet. VFS_VRELE is implemented but not called. A default vfs_vrele was created for fs implementations that use the standard vnode management routines. VFS_VRELE implementations were made for the following file systems: Standard (vfs_vrele) ffs mfs nfs msdosfs devfs ext2fs Custom union umapfs Just EOPNOTSUPP fdesc procfs kernfs portal cd9660 These implementations may change as VOP changes are implemented. In the next phase, in the vop implementations calls to vrele and the vrele part of vput will be moved to the top layer vfs_vnops and made visible to all layers. vput will be replaced by unlock in these cases. Unlocking will still be done in the per fs layer but the refcount decrement will be triggered at the top because it doesn't hurt to hold a vnode reference a little longer. This will have minimal impact on the structure of the existing code. This will only be done for vnode arguments that are released by the various fs vop implementations. Wider use of VFS_VRELE will likely require restructuring of the code. Reviewed by: phk, dyson, terry et. al. Submitted by: Michael Hancock <michaelh@cet.co.jp> Notes: svn path=/head/; revision=33964
