patches to 2.4.18

patches to 2.4.18

[Jim Thompson]

Is the recommended course of action to simply replace the driver set
in 2.4.18 (or 2.4.19) with what is found at
ftp://ftp.uk.linux.org/pub/people/dwmw2/mtd/cvs/

We're currently using
http://ftp.debian.org/debian/pool/main/m/mtd/mtd_20011217.orig.tar.gz,
but there seem to be a few... issues.

Also, I (like so many others lately), had to comment out the call to
invalidate_device() in mtdblock.c::mtdblock_release() in order to get
my root filesystem (jffs2 on mtdblock on Intel Strataflash) to mount.

I note that the call is still there in the CVS vsion:
  ftp://ftp.uk.linux.org/pub/people/dwmw2/mtd/cvs/mtd/drivers/mtd/mtdblock.c

and we are getting crashes on halt/reboot if we've modified the
filesystem.

Similar questions about jffs2 have been asked:

	http://mhonarc.axis.se/jffs-dev/msg01297.html

With no apparent answer.

anyone with clue to offer?

Jim

Eep. That was removed from CVS long ago, but was added back again. I've now 
removed it again.

More details please.

For the MTD drivers, the code in 2.4.19-pre is probably the best option 
unless you need the new features I held back for 2.4.20-pre. For JFFS2, you 
should be using the code from the jffs2-2_4-branch in CVS. I _think_ that's 
all been sent to Marcelo for 2.4.19 though.

I'm a newbie with CVS... but the paragraph above makes it sound like there
are a number of different branches, and that the one I need is called
2.4.19-pre.  So I tried:

cvs -d:pserver:anoncvs@cvs.infradead.org:/home/cvs co -r 2.4.19-pre mtd

but got back:

cvs [server aborted]: Numeric tag 2.4.19-pre contains characters other than digits and '.'

So I tried:

cvs -d:pserver:anoncvs@cvs.infradead.org:/home/cvs co -r 2.4.19 mtd

and that seemed to work i.e. it said the right things about "Updating mtd"
etc but actually it downloaded nothing ;-(

Help much appreciated!

No, it means the mtd code in kernel version 2.4.19-pre, which does not 
contain the latest changes.

Latest changes are available from

cvs -d:pserver:anoncvs@cvs.infradead.org:/home/cvs co mtd
