The following changes since commit 347e9f5043c89695b01e66b3ed111755afcf1911: Linux 6.16-rc6 (2025-07-13 14:25:58 -0700) are available in the Git repository at: https://git.kernel.org/pub/scm/linux/kernel/git/cel/linux.git tags/nfsd-6.17 for you to fetch changes up to e339967eecf1305557f7c697e1bc10b5cc495454: nfsd: Drop dprintk in blocklayout xdr functions (2025-07-14 12:46:50 -0400) ---------------------------------------------------------------- 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. ---------------------------------------------------------------- Christoph Hellwig (3): sunrpc: simplify xdr_init_encode_pages sunrpc: simplify xdr_partial_copy_from_skb sunrpc: unexport csum_partial_copy_to_xdr Chuck Lever (14): NFSD: Rename a function parameter NFSD: Make nfsd_genl_rqstp::rq_ops array best-effort NFSD: Remove the cap on number of operations per NFSv4 COMPOUND NFSD: Remove definition for trace_nfsd_file_unhash_and_queue NFSD: Remove definitions for unused trace_nfsd_file_lru trace points NFSD: Remove definition for trace_nfsd_file_gc_recent NFSD: Remove definition for trace_nfsd_ctl_maxconn NFSD: Clean up kdoc for nfsd_file_put_local() NFSD: Clean up kdoc for nfsd_open_local_fh() NFSD: Use vfs_iocb_iter_read() NFSD: Use vfs_iocb_iter_write() Revert "NFSD: Force all NFSv4.2 COPY requests to be synchronous" NFSD: Access a knfsd_fh's fsid by pointer NFSD: Simplify struct knfsd_fh Dai Ngo (3): NFSD: Offer write delegation for OPEN with OPEN4_SHARE_ACCESS_WRITE NFSD: release read access of nfs4_file when a write delegation is returned NFSD: detect mismatch of file handle and delegation stateid in OPEN op Gustavo A.
