Linus Torvalds 2831fa8b8b NFSD 7.0 Release Notes
Neil Brown and Jeff Layton contributed a dynamic thread pool sizing
 mechanism for NFSD. The sunrpc layer now tracks minimum and maximum
 thread counts per pool, and NFSD adjusts running thread counts based
 on workload: idle threads exit after a timeout when the pool exceeds
 its minimum, and new threads spawn automatically when all threads
 are busy. Administrators control this behavior via the nfsdctl
 netlink interface.
 
 Rick Macklem, FreeBSD NFS maintainer, generously contributed server-
 side support for the POSIX ACL extension to NFSv4, as specified in
 draft-ietf-nfsv4-posix-acls. This extension allows NFSv4 clients to
 get and set POSIX access and default ACLs using native NFSv4
 operations, eliminating the need for sideband protocols. The feature
 is gated by a Kconfig option since the IETF draft has not yet been
 ratified.
 
 Chuck Lever delivered numerous improvements to the xdrgen tool.
 Error reporting now covers parsing, AST transformation, and invalid
 declarations. Generated enum decoders validate incoming values
 against valid enumerator lists. New features include pass-through
 line support for embedding C directives in XDR specifications,
 16-bit integer types, and program number definitions. Several code
 generation issues were also addressed.
 
 When an administrator revokes NFSv4 state for a filesystem via the
 unlock_fs interface, ongoing async COPY operations referencing that
 filesystem are now cancelled, with CB_OFFLOAD callbacks notifying
 affected clients.
 
 The remaining patches in this pull request are clean-ups and minor
 optimizations. Sincere thanks to all contributors, reviewers,
 testers, and bug reporters who participated in the v7.0 NFSD
 development cycle.
