Thanks Shmulik - I did not have time to look at the patches, but the
overall description looks good. I will review the patches as soon as I
can. Thanks for making sense of this mess.

But one more think is the mtd web-site. I've grepped for '1%' and there
are plenty of them. I've changed them all to 2% more or less
mechanically - only cleaned up one section by removing out-of-date
information. Would you please grep for '2%' and review if the
information there is reasonable? Also, would you please add some more
info to this FAQ entry:

Or even better if you could write a separate section for this stuff in
the documentation, then you could remove that FAQ entry completely.

Thanks a lot!

Best Regards,
Artem Bityutskiy
