This looks sane to me, although I'll admit that JFFS1 is a vague and 
distant memory - I have enough trouble remembering the details of JFFS2 :)

Unless someone else objects to it shortly, feel free to go ahead and commit
it. Please could I ask you to make the layout of the new code match what was
there already though? Curly braces on the same line as the if() statement, 
etc. I'll refrain from being pedantic about printks without priorities as 
that _does_ actually match the existing code :)
