Nonetheless, I don't mine resetting the version number of a patchset after dropping RFC. Actually, I personally rather prefer resetting the version number. Anyway, I don't care that much. Please use any way that you feel more comfortable :) Please just keep the number monotonically increase. Thanks, SJ > > Honggyu
