Subject: [PATCH 0/2] optimise bvec/bio iteration
Date: Tue, 24 Nov 2020 17:58:11 +0000 [thread overview]
Message-ID: <cover.1606240077.git.asml.silence@gmail.com> (raw)
This adds simpler versions of bvec_iter_advance() and bio_advance_iter()
(i.e. *_single()), that are faster but work with the restriction that
@bytes shouldn't be more than available in the current bvec segment.
That covers most of bvec/bio iteration/foreach, that are massively
inlined, and thus also nicely shrinks binary.
Others non core-block users might be updated on case by case basis
(if applicable) after the change is merged.
Pavel Begunkov (2):
block: optimise for_each_bvec() advance
bio: optimise bvec iteration
