[v3,for-next,0/5] RDMA/hns: Refactor process of buffer allocation and calculation

Message

Weihang Li April 26, 2020, 6:42 a.m. UTC

Patch #1 and #2 aim to use MTR interfaces for PBL buffer instead of MTT,
and after this, MTT can be removed completely. Patch #3 and #5 refactor
buffer size calculation process for WQE and SRQ. #4 can be considered as a
preparation for #5, which just moves code of SRQ together to a more
suitable place.

This series looks huge, but most of the modification is to replace and
remove old interfaces, and patch #4 also contribute a lot. Actually, the
original logic is not changed so much.

Changes since v2:
- Just do a rebase to current for-next branch.

Changes since v1:
- Remove meaningless judgment of count in some inline functions in #3.
- Add more information into commit messages of #3 and #5.
