Please, send proper Linux kernel patches. Hints:

1. Make a separate patch pere change, so that on modification is done by
one patch. In your case, one buffer improvement pere patch.
2. Write good commit message.
3. Use git format-patch to create patches.

No, please just make buffer size to be ubi->max_write_size. Kill this
constant.

Similarly, just use ubi->max_write_size instead.
