Nov. 94		:	Work begins.

Dec. 94 v0.01	:	First version, directly changing buffers' device
			in getblk, bread and co. No swap. Added an entry
			in /proc for debugging purpose.

Jan. 95 v0.10	:	Reworked the whole thing, due to some FS problems
			with buffers on the same virtual device not belonging
			to the same real device. Gave up on buffers device
			change, and now using request device, which is
			obviously better.

Jan. 15/95 v0.11:	FS is now working fine (using an ext2). Swap added
			but not yet tested.

Jan. 21/95 v0.12:	Fixed a king-size bug in swap, now working flawlessly.
			Some cosmetic changes to /proc/mdstat. Also cleaned
			up md tools and wrote man page.

Feb. 14/95 v0.13:	Fixed a bug preventing from using any md_dev other
			than md0 ! Some checking added in the kernel.
			Real devices now look like mounted when added to a
			md_dev (use an inode as a lock, so it works with
			fs_may_mount). Updated md tools (now behaving a bit
			like mount). Man page is more confusing.
