[ENBD] fr1

[Peter T. Breuer]

I have extracted the intelligent raid1 code in enbd 2.4.31 into a
separate driver, provisionally called fr1 (fast raid 1). It compiles
and loads but I haven't dared try it yet. I wrote it to use the
standard raidtools ioctls, which means it has to take the MD major
(9), although that's adjustable with a module param (major=..).

The driver is about 2000 lines long, and I will begin debugging
it. I'll put it up on the ftp site, and anyone who wants to help can
gaze at it thoughtfully. I know one needs to demonstrate how something
works in order to get help, but I'll put it up now and get it to
the workable state in a few days.

It'll be in ftp://oboe.it.uc3m.es/pub/Programs/fr1.tgz
