Thanks Soumya,
I've been plugging away at the same thing:
https://github.com/jtlayton/nfs-ganesha/commits/deleg
I respun your patch to add lease_op2, and added some code to wire up
ganesha to the new delegation facility in libcephfs that I've been
working on. I've been able to coax ganesha to hand out delegations with
the above set + an appropriate config file. That part has been fairly
straightforward so far.
The difficult part here is handling recalls. My first attempt at it in
the branch above is wrong, I think, so I'm looking more closely today at
the up_ops stuff (spoiler -- it's quite complicated with the layered
FSAL approach).
