* Simplify cdevsw registration.Poul-Henning Kamp1999-05-311-11/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The cdevsw_add() function now finds the major number(s) in the struct cdevsw passed to it. cdevsw_add_generic() is no longer needed, cdevsw_add() does the same thing. cdevsw_add() will print an message if the d_maj field looks bogus. Remove nblkdev and nchrdev variables. Most places they were used bogusly. Instead check a dev_t for validity by seeing if devsw() or bdevsw() returns NULL. Move bdevsw() and devsw() functions to kern/kern_conf.c Bump __FreeBSD_version to 400006 This commit removes: 72 bogus makedev() calls 26 bogus SYSINIT functions if_xe.c bogusly accessed cdevsw[], author/maintainer please fix.

* Divorce "dev_t" from the "major|minor" bitmap, which is now calledPoul-Henning Kamp1999-05-111-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | udev_t in the kernel but still called dev_t in userland. Provide functions to manipulate both types: major() umajor() minor() uminor() makedev() umakedev() dev2udev() udev2dev() For now they're functions, they will become in-line functions after one of the next two steps in this process. Return major/minor/makedev to macro-hood for userland. Register a name in cdevsw[] for the "filedescriptor" driver. In the kernel the udev_t appears in places where we have the major/minor number combination, (ie: a potential device: we may not have the driver nor the device), like in inodes, vattr, cdevsw registration and so on, whereas the dev_t appears where we carry around a reference to a actual device. In the future the cdevsw and the aliased-from vnode will be hung directly from the dev_t, along with up to two softc pointers for the device driver and a few houskeeping bits. This will essentially replace the current "alias" check code (same buck, bigger bang). A little stunt has been provided to try to catch places where the wrong type is being used (dev_t vs udev_t), if you see something not working, #undef DEVT_FASCIST in kern/kern_conf.c and see if it makes a difference. If it does, please try to track it down (many hands make light work) or at least try to reproduce it as simply as possible, and describe how to do that. Without DEVT_FASCIST I belive this patch is a no-op. Stylistic/posixoid comments about the userland view of the <sys/*.h> files welcome now, from userland they now contain the end result. Next planned step: make all dev_t's refer to the same devsw[] which means convert BLK's to CHR's at the perimeter of the vnodes and other places where they enter the game (bootdev, mknod, sysctl).

* I got tired of seeing all the cdevsw[major(foo)] all over the place.Poul-Henning Kamp1999-05-081-2/+2
| | | | | | | | | | | Made a new (inline) function devsw(dev_t dev) and substituted it. Changed to the BDEV variant to this format as well: bdevsw(dev_t dev) DEVFS will eventually benefit from this change too. Notes: svn path=/head/; revision=46676
* Continue where Julian left off in July 1998:Poul-Henning Kamp1999-05-071-2/+2
| | | | | | | | | | | | | | | | | Virtualize bdevsw[] from cdevsw. bdevsw() is now an (inline) function. Join CDEV_MODULE and BDEV_MODULE to DEV_MODULE (please pay attention to the order of the cmaj/bmaj arguments!) Join CDEV_DRIVER_MODULE and BDEV_DRIVER_MODULE to DEV_DRIVER_MODULE (ditto!)

| | | | | | | | | | | | references to them. 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. Notes: svn path=/head/; revision=38909
* 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.

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
