* - FDESC, FIFO, NULL, PORTAL, PROC, UMAP and UNION fileRuslan Ermilov2001-05-231-226/+0
| | | | | | | | | | | | | | | | | | systems were repo-copied from sys/miscfs to sys/fs. - Renamed the following file systems and their modules: fdesc -> fdescfs, portal -> portalfs, union -> unionfs. - Renamed corresponding kernel options: FDESC -> FDESCFS, PORTAL -> PORTALFS, UNION -> UNIONFS. - Install header files for the above file systems. - Removed bogus -I${.CURDIR}/../../sys CFLAGS from userland Makefiles.

* Change the second argument of vflush() to an integer that specifiesIan Dowse2001-05-161-12/+4
| | | | | | | | | | | | | | | | | | | | | | | the number of references on the filesystem root vnode to be both expected and released. Many filesystems hold an extra reference on the filesystem root vnode, which must be accounted for when determining if the filesystem is busy and then released if it isn't busy. The old `skipvp' approach required individual filesystem xxx_unmount functions to re-implement much of vflush()'s logic to deal with the root vnode. All 9 filesystems that hold an extra reference on the root vnode got the logic wrong in the case of forced unmounts, so `umount -f' would always fail if there were any extra root vnode references. Fix this issue centrally in vflush(), now that we can. This commit also fixes a vnode reference leak in devfs, which could result in idle devfs filesystems that refuse to unmount.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | An initial tidyup of the mount() syscall and VFS mount code. This code replaces the earlier work done by jlemon in an attempt to make linux_mount() work. * the guts of the mount work has been moved into vfs_mount(). * move `type', `path' and `flags' from being userland variables into being kernel variables in vfs_mount(). `data' remains a pointer into userspace. * Attempt to verify the `type' and `path' strings passed to vfs_mount() aren't too long. * rework mount() and linux_mount() to take the userland parameters (besides data, as mentioned) and pass kernel variables to vfs_mount(). (linux_mount() already did this, I've just tidied it up a little more.) * remove the copyin*() stuff for `path'. `data' still requires copyin*() since its a pointer into userland. * set `mount->mnt_statf_mntonname' in vfs_mount() rather than in each filesystem. This variable is generally initialised with `path', and each filesystem can override it if they want to. * NOTE: f_mntonname is intiailised with "/" in the case of a root mount.

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 Smith1998-05-061-5/+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
