CommitDate: Fri Jul 30 17:14:57 2021 +0300
[FFS] Remove the FFS/UFS driver
The upstream driver is not maintained and the file system itself
is in a semi-abandoned state.
Originally imported at 3a3ef631d12d8ac7ee2a95abf8c1c6e4815ac1a5
The driver is written by Lee Jae-Hong, updated by Bo Brantén.
ReactOS porting made by Peter Hater and Pierre Schweitzer.
Follow updates at http://www.acc.umu.se/~bosse/
FS Recognizer code is left to keep the FS support as an
installable driver.

- * Each disk drive contains some number of file systems.
- * A file system consists of a number of cylinder groups.
- * Each cylinder group has inodes and data.
- *
- * A file system is described by its super-block, which in turn
- * describes the cylinder groups. The super-block is critical
- * data and is replicated in each cylinder group to protect against
- * catastrophic loss. This is done at `newfs' time and the critical
- * super-block data does not change, so the copies need not be
- * referenced further unless disaster strikes.
- *
- * For file system fs, the offsets of the various blocks of interest
- * are given in the super block as:
- * [fs->fs_sblkno] Super-block
- * [fs->fs_cblkno] Cylinder group block
- * [fs->fs_iblkno] Inode blocks
- * [fs->fs_dblkno] Data blocks
- * The beginning of cylinder group cg in fs, is given by
- * the ``cgbase(fs, cg)'' macro.
- *
- * Depending on the architecture and the media, the superblock may
- * reside in any one of four places. For tiny media where every block
- * counts, it is placed at the very front of the partition. Historically,
- * UFS1 placed it 8K from the front to leave room for the disk label and
- * a small bootstrap. For UFS2 it got moved to 64K from the front to leave
- * room for the disk label and a bigger bootstrap, and for really piggy
- * systems we check at 256K from the front if the first three fail. In
- * all cases the size of the superblock will be SBLOCKSIZE. All values are
- * given in byte-offset form, so they do not imply a sector size. The
- * SBLOCKSEARCH specifies the order in which the locations should be searched.
- *
- * Unfortunately the UFS2/FFSv2 change was done without adequate consideration
- * of backward compatibility. In particular 'newfs' for a FFSv2 partition
- * must overwrite any old FFSv1 superblock at 8k, and preferrably as many
- * of the alternates as it can find - otherwise attempting to mount on a
- * system that only supports FFSv1 is likely to succeed!.
- * For a small FFSv1 filesystem, an old FFSv2 superblock can be left on
- * the disk, and a system that tries to find an FFSv2 filesystem in preference
- * to and FFSv1 one (as NetBSD does) can mount the old FFSv2 filesystem.
- * As a added bonus, the 'first alternate' superblock of a FFSv1 filesystem
- * with 64k blocks is at 64k - just where the code looks first when playing
- * 'hunt the superblock'.
- *
- * The ffsv2 superblock layout (which might contain an ffsv1 filesystem)
- * can be detected by checking for sb->fs_old_flags & FS_FLAGS_UPDATED.
- * This is the default suberblock type for NetBSD since ffsv2 support was added.
