This set is a resend that includes some extra patches that
piled up in the meantime.
I still have some patches in the pipe (including initiator/target
support for remote invalidate) but I'm targeting those to 4.4
This patch set includes:
- Small fixes for bugs encountered in testing
- Small fixes detected by static checkers
- Memory registration code path rework (consolidate to
a single code path that branches only at the actual registration
FRWR vs. FMR). This reduces code duplication that exists in current code.
- Larger IO transfer size support (up to 8MB at the moment) depending on
the device capabilities.
- Optimize Io path by chaining send work requests and posting them
only once.
