Do you prefer it to go through s390 tree? The thing is, I've stuff in iov_iter tree that conflicts with it; I'll gladly drop that bit (vfs.git #fixes-s390) in favour of your series (and drop s390 bits from "new iov_iter flavour - ITER_UBUF" in #work.iov_iter - they are not needed anymore). I can put your series into replacement of #fixes-s390, or pull it from whatever static branch you put it into - up to you. Preferences?
