Linus Torvalds f35d170615 NFSD 6.6 Release Notes

I'm thrilled to announce that the Linux in-kernel NFS server now
 offers NFSv4 write delegations. A write delegation enables a client
 to cache data and metadata for a single file more aggressively,
 reducing network round trips and server workload. Many thanks to Dai
 Ngo for contributing this facility, and to Jeff Layton and Neil
 Brown for reviewing and testing it.
 
 This release also sees the removal of all support for DES- and
 triple-DES-based Kerberos encryption types in the kernel's SunRPC
 implementation. These encryption types have been deprecated by the
 Internet community for years and are considered insecure. This
 change affects both the in-kernel NFS client and server.
 
 The server's UDP and TCP socket transports have now fully adopted
 David Howells' new bio_vec iterator so that no more than one
 sendmsg() call is needed to transmit each RPC message. In
 particular, this helps kTLS optimize record boundaries when sending
 RPC-with-TLS replies, and it takes the server a baby step closer to
 handling file I/O via folios.
 
 We've begun work on overhauling the SunRPC thread scheduler to
 remove a costly linked-list walk when looking for an idle RPC
 service thread to wake. The pre-requisites are included in this
 release. Thanks to Neil Brown for his ongoing work on this
 improvement.
