| H A D | uio.h | 8409a0d2 Sun May 02 10:57:37 CDT 2021 Al Viro <viro@zeniv.linux.org.uk> sanitize iov_iter_fault_in_readable()
1) constify iov_iter argument; we are not advancing it in this primitive.
2) cap the amount requested by the amount of data in iov_iter. All
existing callers should've been safe, but the check is really cheap and
doing it here makes for easier analysis, as well as more consistent
semantics among the primitives.
3) don't bother with iterate_iovec(). Explicit loop is not any harder
to follow, and we get rid of standalone iterate_iovec() users - it's
only used by iterate_and_advance() and (soon to be gone) iterate_all_kinds().
