Ouch, so surprised that after all these years someone is doing squashfs/mtdblock
instead of using ubiblock :-)

Can we patch either Kconfig or add some warn_once on mtdblock
usage, suggesting to use ubiblock instead?

a hint in Kconfig makes IMHO sense. Do you want to send a patch?
A warning is too much since on some tiny embedded system with NOR flash mtdblock is still
a good choice.
ubiblock is mostly useful for NAND flash.

I remember there was still some use case(s) for mtdblock but I can't remember
now what was it, perhaps we should document the expectations?
(Is that for JFFS2 to mount?)

a long time ago mount didn't accept character devices, so you had to pass mtdblockX to mount
JFFS2.
This limitation is gone.

OK, let me try to cook a patch for you.

Eze
