Let me add that keeping the write support follows the whole "mechanism,
not policy" kernel motto, doesn't it?

Regarding users, well the option looks like this:

  [ ]     Enable write support (DANGEROUS)

I think any user would think twice before enabling it.

Regaring the maintainability: the implementation is *really* simple,
and won't add much complexity.

Let's not prevent someone from divising a wear level aware block filesystem
and using it on top of ubiblock. And perhaps f2fs already does a good job!
Keeping this support would allow someone to take the lead and get some real
numbers on that.

As I said, the implementation is so simple that it seems a pity to just
drop it.

BTW, v5 (this is v4 which I forgot to add to the subject) is already on the
oven, with the fixes pointed out by Richard.
