*(int *)0=0; doesn't cause an oops on all platforms. That was why BUG() was 
introduced. Probably better just to omit my paranoia checks altogether, 
once we're happy that mtdblock actually works. For now, surround them in 
#ifdef PARANOIA. I thought I'd done that already.

DECLARE_MUTEX_LOCKED wants adding to compatmac.h if it's not already there.

What was the reasoning for removing the 'static' from the declaration of 
thr_wq?

Anyway, it didn't build _only_ on ARM - it built on SH too :)

Uhhh...that would be my stupidity. I forgot to put 'static' back on
the declaration.

Ahh... I'm looking at an older version (the one in 2.4.0-test7).

I re-wrote the debugging such that it is now a configuration
option in the MTD sub-system menu where you choose the level
of verbosity. There a four levels which are defined in the
'include/linux/mtd/mtd.h' that you can use to define the
severity/verbosity of a debug statement.
