David should answer, but from my POW the patches are OK. The "#ifdef
CONFIG_MTD_AFS_PARTS" is ugly. I think it can be just killed, it just
needs an additional patch to silence the kernel (completely untested,
Marc, could you please check it?):

Subject: [PATCH] mtd: be silent when mtd partition parser cannot be found

Currently when we register partitions in 'parse_mtd_partitions()' we accept the
list of parsers we should try. And if one of the parsers was not found we print
a message. Well, first of all this whole idea is bad - look at how many
'part_probes' and 'part_probe_types' variables we have - nearly every driver
defines one. Instead, we should just go through all registered parsers all the
time. But this needs to be worked on separately.

This patch makes life of MTD partitions' users a bit simpler and allows them to
safely request parsers which have not been registered -
'parse_mtd_partitions()' will not print a "not available" message in this
case.

Sorry, I've just been told that I should use the correct form - POV, not
POW :-)

Looks OK to me, as long as people don't miss the information (could make
the "where's my partition gone?" question harder to answer...).

As this change is orthogonal to mine, I suggest this change goes via the
MTD tree, independently from this patch set. I post a v6 later today
(without the #ifdef-ery).

Cheers,

	M.

Fine with me, thanks.

I've pushed my patch to my l2-mtd-2.6.git tree, if dwmw2 accepts it
it'll go upstream.

I've also committed them to my tree too.
