This release introduces support for the CB_RECALL_ANY operation. NFSD can send this operation to request that clients return any delegations they choose. The server uses this operation to handle low memory scenarios or indicate to a client when that client has reached the maximum number of delegations the server supports. The NFSv4.2 READ_PLUS operation has been simplified temporarily whilst support for sparse files in local filesystems and the VFS is improved. Two major data structure fixes appear in this release: * The nfs4_file hash table is replaced with a resizable hash table to reduce the latency of NFSv4 OPEN operations. * Reference counting in the NFSD filecache has been hardened against races. In furtherance of removing support for NFSv2 in a subsequent kernel release, a new Kconfig option enables server-side support for NFSv2 to be left out of a kernel build. MAINTAINERS has been updated to indicate that changes to fs/exportfs should go through the NFSD tree. -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEEKLLlsBKG3yQ88j7+M2qzM29mf5cFAmOXPE4ACgkQM2qzM29m f5faaRAAh7YT5V61afPbfgBybO5AbDzztpZSNjNjLZs78piSnFp6hP75yNtTviwQ 1o7St13/NkCmDaIdGUpr02U01zbM1BDOq2wGckImOJLNSgb7xHV5r4PqkRiFkh0t QYSnwG+wp8fDUJeCL/nAOAu9I9EQUqHzWchxiU/h8ln2hN3rXUlIRSeo17Wy7zkD cNIcoAjTi9fzY3dE6H4r+lZTdNCYH+AdzChmKrHdRZQwq0Xs3FWv4gAMTLbDuD4P B6NDHz0Umn6XnFsJGptwozkwaWeMQw4GyJj/3iUiO8JF209SaoYXMPjJAyG6tYYa fUrgv4UXGeXjigDbLBA5IYxfhX7GXjMQSaj3edhzyrl8P74q4/Cq/8fDUnAZ841m E+TGSCPIQD0QuIjdXxLv9KLY8JNThSfcAt6jr5GBXhPZQr8xpS0BqK/Onr68fgZC Lpull5xN68L4A1B7cf2GNPuMyvkBKxwSGXOehldh/BkvpVMjFwqd4/q5xWC+6CcQ tbOkjTbbSS71nzJwZip0NphaYCa3qQPzKT4SZzn/I4I9W5otbwYBx734Bw46gTDE ZPUXTuJ00VPgX07wbLRahg521Fwzr+8sk1WnVYq82PoaMh1l9FjzLNGouQWBdo3E UzIo/KUfQKmoZce6O723L6OI4ffdK5oMtfaTpe+SiUPpV1lUAcA= =jNlu -----END PGP SIGNATURE----- Merge tag 'nfsd-6.2' of git://git.kernel.org/pub/scm/linux/kernel/git/cel/linux Pull nfsd updates from Chuck Lever: "This release introduces support for the CB_RECALL_ANY operation.
