No idea, I use vim.  Try to mimic existing code, use scripts/Lindent
or read Documentation/CodingStyle.

I think that most users don't want JFFS2 to run in WORM mode.  And for
those users, failing on every write is actually better.  They notice
the problem right away, not just after a while.

People that want WORM mode are the minority and therefore should be
the ones that are inconvenienced.
