Poul-Henning Kamp 20a92a18f1 The remaining part of nmount/omount/rootfs mount changes. I cannot sensibly ... split the conversion of the remaining three filesystems out from the root mounting changes, so in one go: cd9660: Convert to nmount. Add omount compat shims. Remove dedicated rootfs mounting code. Use vfs_mountedfrom() Rely on vfs_mount.c calling VFS_STATFS() nfs(client): Convert to nmount (the simple way, mount_nfs(8) is still necessary). Add omount compat shims. Drop COMPAT_PRELITE2 mount arg compatibility. ffs: Convert to nmount. Add omount compat shims. Remove dedicated rootfs mounting code. Use vfs_mountedfrom() Rely on vfs_mount.c calling VFS_STATFS() Remove vfs_omount() method, all filesystems are now converted. Remove MNTK_WANTRDWR, handling RO/RW conversions is a filesystem task, and they all do it now. Change rootmounting to use DEVFS trampoline: vfs_mount.c: Mount devfs on /. Devfs needs no 'from' so this is clean. symlink /dev to /. This makes it possible to lookup /dev/foo. Mount "real" root filesystem on /. Surgically move the devfs mountpoint from under the real root filesystem onto /dev in the real root filesystem. Remove now unnecessary getdiskbyname(). kern_init.c: Don't do devfs mounting and rootvnode assignment here, it was already handled by vfs_mount.c. Remove now unused bdevvp(), addaliasu() and addalias(). Put the few necessary lines in devfs where they belong. This eliminates the second-last source of bogo vnodes, leaving only the lemming-syncer. Remove rootdev variable, it doesn't give meaning in a global context and was not trustworth anyway. Correct information is provided by statfs(/).		2004-12-07 08:15:41 +00:00
