Re: [PATCH v4 00/11] NFS/RDMA server patches for v4.5

2015-12-24 Thread Chuck Lever 
My functional test suite includes Cthon, iozone, dbench, fio,
multi-threaded builds of git and the Linux kernel, and xfstests.

This patch series passes with NFSv3, NFSv4.0, and now NFSv4.1.

iozone passed on ocrdma device. Link bounce fails to recover iozone
traffic, however failure is not related to this patch series. I am in
processes of finding out the patch which broke it.

[PATCH v4 00/11] NFS/RDMA server patches for v4.5

2015-12-14 Thread Chuck Lever 
Here are patches to support server-side bi-directional RPC/RDMA
operation (to enable NFSv4.1 on RPC/RDMA transports). Thanks to
all who reviewed v1, v2, and v3. This version has some significant
changes since the previous one.

In preparation for Doug's final topic branch, Bruce, I've rebased
these on Christoph's ib_device_attr branch. There were some merge
conflicts which I've fixed and tested. These are ready for your
review.

Also available in the "nfsd-rdma-for-4.5" topic branch of this git repo:

git://git.linux-nfs.org/projects/cel/cel-2.6.git

Or for browsing:

http://git.linux-nfs.org/?p=cel/cel-2.6.git;a=log;h=refs/heads/nfsd-rdma-for-4.5


Changes since v3:
- Rebased on Christoph's ib_device_attr branch
- Backchannel patches have been squashed together
- Memory allocation overhaul to prevent blocking allocation
  when sending backchannel calls


Changes since v2:
- Rebased on v4.4-rc4
- Backchannel code in new source file to address dprintk issues
- svc_rdma_get_context() now uses a pre-allocated cache
- Dropped svc_rdma_send clean up


Changes since v1:

- Rebased on v4.4-rc3
- Removed the use of CONFIG_SUNRPC_BACKCHANNEL
- Fixed computation of forward and backward max_requests
- Updated some comments and patch descriptions
- pr_err and pr_info converted to dprintk
- Simplified svc_rdma_get_context()
- Dropped patch removing access_flags field
- NFSv4.1 callbacks tested with for-4.5 client
