Subject: [PATCH 00/10] block: cleanup on direct access to bvec table(prepare for multipage bvec)
Date: Fri, 8 Dec 2017 21:13:59 +0800 [thread overview]
Message-ID: <20171208131409.11889-1-ming.lei@redhat.com> (raw)
Hi,
This patchse cleans up most of direct access to bvec table in tree, and
these patches are the follow-up of patch1 ~ 16 in the patchset of 'block:
support multipage bvec(V3)'[1].
Changes against [1]:
1) split the cleanup patches from [1]
2) address comments from Christoph:
- introduce bio helpers for dealing with the cleanup
- move bio_alloc_pages() to bcache
[1] https://marc.info/?t=150218197600001&r=1&w=2
Thanks,
Ming
