Subject: [PATCH] caif: don't assume iov_iter type
Date: Wed, 11 Jan 2023 10:42:45 -0800	[thread overview]
Message-ID: <[email protected]> (raw)

From: Keith Busch <[email protected]>

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.
