Um, that repo seems to be based on something earlier than 2.6.36-rc1.
And the real -rc1 already contains most of those commits.

I think there are four commits which aren't already included. Of those,
at least one looks like a bug fix which needs to go into 2.6.36. What
about the others?

The patch from John Ogness is a bug fix. 'configure pages per block for
v2 controller' can be considered a bug fix since before this patch we
relied on some register bits being set correctly by the bootloader.
One patch can wait for the next merge window I think.
I updated the branch to contain the following:

Not sure if David is confused or not, but I'm confused. Could you please
sent 2 separate pull requests: one pull request with stuff you want to
go to 2.6.36 (important fixes) and one request with 2.6.37 material.
Please, base both on the mtd-2.6.git tree. And make it clear in the
subject and the e-mail body which request contains what. This will make
things easier and will probably speed them up. And do not forget to
refresh the patches and add all Acks, if any :-)

Thanks!

The mtd-2.6.git tree seems empty at the moment, so the branch is based
on linus/master.

Ok, please pull for 2.6.36:

I do not know what dwmw2 would answer, but I think it is wrong to send a
pull request based on something which is not in the tree you want to get
it. If dwmw2 pulls your tree, he will also pull all the other stuff, and
then get beaten by Linus for basing things on a random commit.

Anyway, I cherry-picked those 2 patches and put them to my
l2-mtd-2.6.git tree to the for-2.6.36 branch, and will bug dwmw2.

Please, send the rest of your stuff for 2.6.37 as well.

Also, please, use "mtd:" prefix for all your patches.

Hi Artem,

Sascha is away for two weeks, maybe he was in a hurry to get this request out
before he left. We are sorry for the problems that might have caused!

Thanks for doing that!

Will try to get this properly done in the next days.

Thanks again,

FYI, both patches were merged upstream.
