[PATCH v2 0/5] Fix "support large inline thresholds"

[Chuck Lever <chuck.lever@oracle.com>]

Hi Anna-

I've received a number of reports that v4.9 commit 655fec6987be
("xprtrdma: Use gathered Send for large inline messages") causes
NFS/RDMA mounts to fail for devices that have a small max_sge.

This series addresses that problem. Would you consider this series
of bug fixes for v4.10-rc?


Available in the "nfs-rdma-for-4.10-rc" topic branch of this git repo:

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

And for online review:

http://git.linux-nfs.org/?p=cel/cel-2.6.git;a=shortlog;h=refs/heads/nfs-rdma-for-4.10-rc


Changes since v1:
- Rebased on v4.10-rc5
- Renamed some variables for clarity
- Clarified patch descriptions
- Added Tested-by and Reviewed-by tags
