1b4fb5ffd79b iov_iter: teach iterate_{bvec,xarray}() about possible short copies
7491a2bf64e3 iterate_bvec(): expand bvec.h macro forest, massage a bit
5c67aa90cd5c iov_iter: unify iterate_iovec and iterate_kvec
7a1bcb5d255d iov_iter: massage iterate_iovec and iterate_kvec to logics similar to iterate_bvec
f5da83545f4e iterate_and_advance(): get rid of magic in case when n is 0
594e450b3f44 csum_and_copy_to_iter(): massage into form closer to csum_and_copy_from_iter()
f0b65f39ac50 iov_iter: replace iov_iter_copy_from_user_atomic() with iterator-advancing variant
e4f8df86798a [xarray] iov_iter_npages(): just use DIV_ROUND_UP()

28f38db7edbf iov_iter: reorder handling of flavours in primitives
4b6c132b7da6 iov_iter: switch ..._full() variants of primitives to use of iov_iter_revert()
3b3fc051cd2c iov_iter_advance(): use consistent semantics for move past the end
0e8f0d674015 [xarray] iov_iter_fault_in_readable() should do nothing in xarray case
a506abc7b644 copy_page_to_iter(): fix ITER_DISCARD case
