I made some time for this one. We'll see about the pairing one
(hopefully trivial? but I'm not sure if there's value in merging without
users).

Thanks. I only added one trivial fixup that checkpatch.pl's spelling.txt
(what??) caught:

diff --git a/drivers/mtd/nand/nand_base.c b/drivers/mtd/nand/nand_base.c
index 7a00245ebada..e5718e5ecf92 100644

}

I added a small note in the merge commit about the BBT changes you made.
That's an especially fragile piece of code I think (and used by every
NAND driver), but it looked OK to me.

Well, I already posted UBI patches using this API, and that'd be easier
if the interface is already available (that would solve cross-tree
dependencies).

Oh, I completely forgot about this important change.

Thanks for fixing the typo and adding more information in the merge
message.
