MTD partitioning rewrite finished

MTD partitioning rewrite finished

[Jörn Engel]

Hi!

The code has matured enough on my machine that normal people might try
it, too. You can download a patch against 2.4.13 now, I don't have to
scare away normal users anymore. :)
I also truncated the patch into several smaller ones as the mapping
stuff and the partition parser are optional. 40k is still plenty.

Here are the links for the web page and the direct download:
http://wh.fh-wedel.de/~joern/software/kernel/
http://wh.fh-wedel.de/~joern/software/kernel/mtd_je.patch.2.4.13

PS: Eric, I cc'd you as you said you had a non-academic use for this
stuff. It would be nice to get some feedback. "works" is enough,
"breaks at this point" is better, "this code looks odd" would really
help me to improve the code and my style.

Hi!

Kernel 2.4.14 is out, I adjusted my patches a bit and I found and
corrected some bugs. None of the bugs were serious, though. You might
have been unable to compile, but if you were, everything should have
worked fine.

Bug in mtdblock_ro

[Simon Barber]

the call in mtdblock_request to MTD_READ/WRITE passes nr_sectors, it should
pass current_nr_sectors.

Could you quickly add, what version has this problem? The filename
should be enough. When I get back from vacation (Thursday), I will
have a look at it.

I'm travelling right now - so I can't, sorry - but it's a version I checked
out from the anon CVS a few days (maybe 10) ago. With this bug fix it works
great for me. Without the fix I get a kernel panic on trying to mount a
mtd_ro partition as rootfs.

Erwin, this appears to be your code, if MODULE_AUTHOR is correct. Can
you have a look at it?
And David, Erwin, do you mind if I indent the request function to
Linus' beloved style? Makes reading so much easier.
