[PATCH] caif: don't assume iov_iter type

From: Keith Busch
Date: Wed Jan 11 2023 - 13:43:07 EST


From: Keith Busch <kbusch@xxxxxxxxxx>

The details of the iov_iter types are appropriately abstracted, so
there's no need to check for specific type fields. Just let the
abstractions handle it.

This is preparing for io_uring/net's io_send to utilize the more
efficient ITER_UBUF.
