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.

* This commit fixes various 64bit portability problems required forDoug Rabson1998-06-071-2/+2
| | | | | | | | | | | | | FreeBSD/alpha. The most significant item is to change the command argument to ioctl functions from int to u_long. This change brings us inline with various other BSD versions. Driver writers may like to use (__FreeBSD_version == 300003) to detect this change. The prototype FreeBSD/alpha machdep will follow in a couple of days time. Notes: svn path=/head/; revision=36735
* As described by the submitter:Mike Smith1998-05-061-4/+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.

* The intent is to get rid of WILLRELE in vnode_if.src by makingMike Smith1998-03-011-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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

| | | | | | | | | | | Note that an unload facility should be used to call rm_at_exit() (if procfs is being loaded as an LKM and is subsequently removed), but it was non-obvious how to do this in the VFS framework. Reviewed by: Julian Elischer Notes: svn path=/head/; revision=31618

* Fixed panic that resulted from mmaping files in kernfs and procfs. ADavid Greenman1995-05-251-2/+4
| | | | | | | | | | | | | regular user could panic the machine with a simple "tail /proc/curproc/mem" command. The problem was twofold: both kernfs and procfs didn't fill in the mnt_stat statfs struct (which would later lead to an integer divide fault in the vnode pager), and kernfs bogusly paniced if a bmap was attempted.
