MTD in kernel 2.4.9

MTD in kernel 2.4.9

[Thomas Eschenbacher]

Hi there,

just a newbie question: is there a way to get the current cvs version of
mtd/jffs2 working with kernel 2.4.9?

I can't find any patch for current kernels and if I just spread all the
files/dirs into their destination in the kernel source I can no longer
compile and earn hundreds of error messages.

I'd like to use JFFS2 and I have to boot from it, so compiling separate
from the kernel and making modules is not possible.

Is it possible to use the current JFFS2 with the 2.4.9's mtd drivers -
or let's say: is that mtd stuff in 2.4.9 "new enough" ?

thanks,
   Thomas.

It generally ought to work, although I'm not building JFFS2 against
2.4.9 so I haven't merged the complete_and_exit() fix yet. Other than that, 
what breaks?

The complete_and_exit() problem I experienced was fixed in the 2.4.9 AC 
kernel by adding the wait queue head initialization just before forking the 
GC thread in jffs2_start_garbage_collect_thread(). That fixed the crashing
GC thread problem in unmount.

I haven't tried copying mtd CVS files over Linus kernels but on current
AC kernels straight copying won't work. At least it will complain about
missing up_and_exit().

It seems that Alan has fixed that in his patch-2.4.9-ac9.gz. JFFS2 now
compiles without complaining and even the entries in Configure.in and
the Makefile are present!

I would think so. I have not tried 2.4.9, but 2.4.5 works just fine.
