has implicit fence.
If invalidate is issued before read
You're correct. And this bug appears to be in the current upstream code as
well. If
an
IB_WR_LOCAL_INV wr is used, it must include IB_SEND_FENCE to fence it until
the prior
read
completes.
Good catch! I'll post V4 soon.
Any chance that can be handled as a separate patch

This patch refactors the NFSRDMA server marshalling logic to
remove the intermediary map structures. It also fixes an existing bug
where the NFSRDMA server was not minding the device fast register page
list length limitations.
I've also made a git repo available with these patches on top of
