[PATCH 00/10] Improve 9P/RDMA

[Simon Derr <simon.derr@bull.net>]

Hi,

This is a series of patches which aim to make 9P/RDMA better.

Eric Van Hensbergen asked that I send them to netdev to get a wider review.

They deal mainly with fcall allocation/deallocation, RQ locking,
error handling, and above all buffer management.
This has been tested intensively with the nfs-ganesha server.

Regards,

	Simon
