* Retire LFS.Poul-Henning Kamp1998-01-3015-5017/+0
| | | | | | | | | | | | | | | If you want to play with it, you can find the final version of the code in the repository the tag LFS_RETIREMENT. If somebody makes LFS work again, adding it back is certainly desireable, but as it is now nobody seems to care much about it, and it has suffered considerable bitrot since its somewhat haphazard integration.

* Make all file-system (MFS, FFS, NFS, LFS, DEVFS) related option new-style.Eivind Eklund1998-01-241-1/+3
| | | | | | | | | | | This introduce an xxxFS_BOOT for each of the rootable filesystems. (Presently not required, but encouraged to allow a smooth move of option *FS to opt_dontuse.h later.) LFS is temporarily disabled, and will be re-enabled tomorrow. Notes: svn path=/head/; revision=32726

| | | | | | | | | | | | | | | | | | | Ever since I first say the way the mount flags were used I've hated the fact that modes, and events, internal and exported, and short-term and long term flags are all thrown together. Finally it's annoyed me enough.. This patch to the entire FreeBSD tree adds a second mount flag word to the mount struct. it is not exported to userspace. I have moved some of the non exported flags over to this word. this means that we now have 8 free bits in the mount flags. There are another two that might well move over, but which I'm not sure about. The only user visible change would have been in pstat -v, except that davidg has disabled it anyhow. I'd still like to move the state flags and the 'command' flags apart from each other.. e.g. MNT_FORCE really doesn't have the same semantics as MNT_RDONLY, but that's left for another day.

* Another VFS cleanup "kilo commit"Poul-Henning Kamp1997-10-164-24/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1. Remove VOP_UPDATE, it is (also) an UFS/{FFS,LFS,EXT2FS,MFS} intereface function, and now lives in the ufsmount structure. 2. Remove VOP_SEEK, it was unused. 3. Add mode default vops: VOP_ADVLOCK vop_einval VOP_CLOSE vop_null VOP_FSYNC vop_null VOP_IOCTL vop_enotty VOP_MMAP vop_einval VOP_OPEN vop_null VOP_PATHCONF vop_einval VOP_READLINK vop_einval VOP_REALLOCBLKS vop_eopnotsupp And remove identical functionality from filesystems 4. Add vop_stdpathconf, which returns the canonical stuff. Use it in the filesystems. (XXX: It's probably wrong that specfs and fifofs sets this vop, shouldn't it come from the "host" filesystem, for instance ufs or cd9660 ?) 5. Try to make system wide VOP functions have vop_* names. 6. Initialize the um_* vectors in LFS. (Recompile your LKMS!!!) Notes: svn path=/head/; revision=30492

* VFS mega cleanup commit (x/N)Poul-Henning Kamp1997-10-165-59/+45
| | | | | | | | | | | | | | | | | | | | | | | | | | 1. Add new file "sys/kern/vfs_default.c" where default actions for VOPs go. Implement proper defaults for ABORTOP, BWRITE, LEASE, POLL, REVOKE and STRATEGY. Various stuff spread over the entire tree belongs here. 2. Change VOP_BLKATOFF to a normal function in cd9660. 3. Kill VOP_BLKATOFF, VOP_TRUNCATE, VOP_VFREE, VOP_VALLOC. These are private interface functions between UFS and the underlying storage manager layer (FFS/LFS/MFS/EXT2FS). The functions now live in struct ufsmount instead. 4. Remove a kludge of VOP_ functions in all filesystems, that did nothing but obscure the simplicity and break the expandability. If a filesystem doesn't implement VOP_FOO, it shouldn't have an entry for it in its vnops table. The system will try to DTRT if it is not implemented. There are still some cruft left, but the bulk of it is done. 5. Fix another VCALL in vfs_cache.c (thanks Bruce!) Notes: svn path=/head/; revision=30474

| | | | | | | | | | | | | | | | | | | | | | | | Introduce VFREE which indicates that vnode is on freelist. Rename vholdrele() to vdrop(). Create vfree() and vbusy() to add/delete vnode from freelist. Add vfree()/vbusy() to keep (v_holdcnt != 0 || v_usecount != 0) vnodes off the freelist. Generalize vhold()/v_holdcnt to mean "do not recycle". Fix reassignbuf()s lack of use of vhold(). Use vhold() instead of checking v_cache_src list. Remove vtouch(), the vnodes are always vget'ed soon enough after for it to have any measuable effect. Add sysctl debug.freevnodes to keep track of things. Move cache_purge() up in getnewvnodes to avoid race.

* Fix a problem with the VN device. Specifically, the VN device canJohn Dyson1997-06-152-2/+13
| | | | | | | | | | | | | cause a problem of spiraling death due to buffer resource limitations. The vfs_bio code in general had little ability to handle buffer resource management, and now it does. Also, there are a lot more knobs for tuning the vfs_bio code now. The knobs came free because of the need that there always be some immediately available buffers (non-delayed or locked) for use. Note that the buffer cache code is much less likely to get bogged down with lots of delayed writes, even more so than before. Notes: svn path=/head/; revision=26664

* Removed `volatile' from declaration of `time', and removed the resultingBruce Evans1997-03-221-2/+2
| | | | | | | | | | | null casts. `time' is nonvolatile for accesses within a region locked by splclock()/splx(). Accesses outside such a region are invalid, and splx() must have the side effect of potentially changing all global variables (since there are hundreds of sort of volatile variables like `time'), so declaring `time' as volatile didn't have any real benefits.
