Something I noticed is that the printk cleanups could look a bit nicer if you used #define pr_fmt(fmt) "uclinux[mtd]: " fmt and then pr_notice et al. But maybe this is only subjective. Also I'm not sure if all the comments are still correct with my change. (And btw, your mailer is broken regarding line breaking and non-ascii characters.) Best regards Uwe

I haven't picked it up. I assumed Artem would, but I have not seen any response from him on this yet. I thought you where going to put a comment in there, http://mailman.uclinux.org/pipermail/uclinux-dev/2012-May/051873.html In any case, Uwe, that thread states what the issue is when it came up a few months back. Regards Greg
