NFSD 6.17 Release Notes

NFSD is finally able to offer write delegations to clients that open
files with O_WRONLY, thanks to patches from Dai Ngo. We're expecting
this to accelerate a few interesting corner cases.

The cap on the number of operations per NFSv4 COMPOUND has been
lifted. Now, clients that send COMPOUNDs containing dozens of
operations (for example, a long stream of LOOKUP operations to walk
a pathname in a single round trip) will no longer be rejected.

This release re-enables the ability for NFSD to perform NFSv4.2 COPY
operations asynchronously. This feature has been disabled to
mitigate the risk of denial-of-service when too many such requests
arrive.

Many thanks to the contributors, reviewers, testers, and bug
reporters who participated during the v6.17 development cycle.
