    Subject[net-next][PATCH 00/13] RDS: Major clean-up with couple of new features for 4.6
    Date
    Series is generated against net-next but also applies against Linus's tip
    cleanly. The diff-stat looks bit scary since almost ~4K lines of code is
    getting removed.

    Brief summary of the series:

    - Drop the stale iWARP support:
    RDS iWarp support code has become stale and non testable for
    sometime. As discussed and agreed earlier on list [1], am dropping
    its support for good. If new iWarp user(s) shows up in future,
    the plan is to adapt existing IB RDMA with special sink case.
    - RDS gets SO_TIMESTAMP support
    - Long due RDS maintainer entry gets updated
    - Some RDS IB code refactoring towards new FastReg Memory registration (FRMR)
    - Lastly the initial support for FRMR

    RDS IB RDMA performance with FRMR is not yet as good as FMR and I do have
    some patches in progress to address that. But they are not ready for 4.6
    so I left them out of this series.

    Also am keeping eye on new CQ API adaptations like other ULPs doing and
    will try to adapt RDS for the same most likely in 4.7 timeframe.

    Entire patchset is available below git tree:
    git://git.kernel.org/pub/scm/linux/kernel/git/ssantosh/linux.git for_4.6/net-next/rds

    Feedback/comments welcome !!
