Great, seen it coming down to linux-next :)

You already did all the work for me in linux-next, thanks.

In the patch following the mail, it was in one of Mike's last remarks.

Ah, this one gives me trouble. I made that function so that future evolutions of
MTD api can cope with hardware knowing how many times a block was erased.

My proposition is to make a sysfs entry which will dump the list of all blocks
(from 0 to 2047 for docg3), and for each block print the number of erases. This
will clear the warning, and can be used for very specialized userspace
applications when they choose which block to erase.
This will be another patch I didn't do yet.

I don't have that warning with C=1.
Moreover, the line (630) in l2-mtd-git or linux-next points towards a comment
line. I tried to have a peek at all "syns" usage and it seems correct to me.
So let's think this was a transient error in the whole patch serie.

Roger, single little patch. Don't worry, I think the big work is over for
docg3 ... now Mike's docg3 will be comming soon :)
