Subject: let import_iovec deal with compat_iovecs as well v2
Date: Mon, 21 Sep 2020 16:34:23 +0200 [thread overview]
Message-ID: <[email protected]> (raw)
Hi Al,
this series changes import_iovec to transparently deal with comat iovec
structures, and then cleanups up a lot of code dupliation.
Changes since v1:
- improve a commit message
- drop a pointless unlikely
- drop the PF_FORCE_COMPAT flag
- add a few more cleanups (including two from David Laight)
