[PATCH] 2.4.18-26.7.x /proc/mdstat seq_file

I figured I would follow proper protocol and put PATCH in the subject
line.  As stated in my previous email, this patch fixes my problem of
kernel OOPS with a large number of software RAID arrays (I have 27).
Below is the text from the original mail.

-------------------------------------------

With the help of Martin Bligh, Kevin Fleming, and Randy Dunlap, it looks
like this problem is related to the large size of the information
presented in /proc/mdstat and it overflowing the 4k page boundary.

With Kevin's patch from last week and some help from Randy, I patched
the md code in Red Hat 2.4.18-26.7.x to use the seq_file interface for
mdstat.  I've attached the patch.  As with Kevin's patch, it touches
almost everything in drivers/md, as well as adding the necessary methods
to fs/seq_file.c and include/linux/seq_file.h.

I'm currently testing raid1 and raid0 and it seems to work well.  No
panics yet!!! :)  I currently have 26 RAID1 arrays and a big RAID0
stripe across that and I'm running some I/O tests on it now to make sure
that it is stable.  

I haven't tested the raid5, linear, or multipath code, so someone might
want to test that out before using it in production :)

As Kevin indicated in his mail, I can post the patch to a web site if
attachments are a problem.

Thanks to everyone for their help.

Regards,
Andy.
