The RPC transport switch patches are almost fully integrated into
mainline. The xprtrdma piece is what is not there yet.
OK, has the xprtrdma piece been reviewed by the community? What, if
anything, is preventing the code from being included in -mm for wider
testing?
Some of the main NFS client developers (Trond, the CITI-UM developers,
myself) have reviewed previous versions of this code, and have
recommended a number of changes. I haven't heard anything recently from
the NetApp engineers working on this. We are waiting for them to
publish again, but I think they are waiting for the last of the
transport switch patches to trickle into mainline (which should be ready
with the release of 2.6.21). I know they have been working with a
handful of test sites and have achieved good performance results.
Has xprtrdma inclusion/progress been discussed on some other mailing
list?
Not yet, but the place that is likely to occur is [EMAIL PROTECTED]
