Updates since v3:
- Rebased on v3.15-rc6
- Patch description updated in "xprtrdma: Remove Tavor ..."
- Comment changed in "xprtrdma: Remove BOUNCEBUFFERS ..."
- Shirley's ACL patch applied
- Six patches added to improve speed and robustness of NFS/RDMA
reconnect
More work is needed to improve reconnect behavior. I have a patch
(not included here) to re-marshal pending RPCs after a disconnect.
It is a definite improvement, but some details still need to be
addressed.
Please review and test. Pull from the "nfs-rdma-client" branch of
my git repo:
