Poul-Henning Kamp cec0f20ce7 VFS mega cleanup commit (x/N) ... 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!)		1997-10-16 10:50:27 +00:00
