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. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEKLLlsBKG3yQ88j7+M2qzM29mf5cFAmmJ8kAACgkQM2qzM29m f5ejCQ//RdoWNgN1VZdNoUrh1tm1Fhi1YN/RJS26G25OxgTBc3/qtGxrpW+ZAW6+ mIAJ2bT/l66741drki4/x6WJU4OMI/4mJxrLd0WCb1POaeRQWnL1MdzNY+IP/QZv 3DgcTv1T6FKE7pFmAqW0nFPCgaK+vlR+fo4uJognbB6+hZB3HlrLkfeZOWMAmchC y3U6nzrtP+IljAtdzKZ120E+LHp0PtTbJwPCPSt3/FR/dkA0DcjnOS9jybIYlJOu 0ByX24BcrW/c3rJUdL8lL4G7gsPWjdARqczFiN8sufI9Q3zlHOxtYdUT7BNjd+04 jcSKLlAXwcbNcK2f54B/QFKmNxllvoHLB3wo2hfEPig4LQELuxcUHYxmmD4vNKen lp6zmaLq3PiRGlew6eLRFxRxbdLds+9l0xjXV+J+rtQmjppXdXUoVNMm+D+tD6bF T5TUq4WNCGJIrpkR7pdF7uMD51s8fphvaDxOCjhSi3WHAtZAhOR8HFUU97qddM34 KqF6Gph3tN/C4oNb8kKvzxBRpRhHIzKHZbreiu5fZr9pPe9IRBHnn/Dg4p/yYQcw K3/y1EnKrIlprfbFFkY1LzNFpf309uoZTVzwBcMfSJVsFgUqWD7KHJ/rmCJQ/pS6 k0+YLRoUmtUHDYk2QNlstlt7r6FwA0d2GjT8n7viGoNQ3PA7rJQ= =hqla -----END PGP SIGNATURE----- Merge tag 'nfsd-7.0' of git://git.kernel.org/pub/scm/linux/kernel/git/cel/linux Pull nfsd updates from Chuck Lever: "Neil Brown and Jeff Layton contributed a dynamic thread pool sizing mechanism for NFSD.
