Hi, This v6 changes include: - Quite a bit of rebasing to eliminate intermediate steps that include throwaway code (thanks to Jeff Layton for calling those out). - Moved the Kconfig changes to the end of the series to ensure that localio cannot be enabled until the code is feature complete. - Removed needless nfsd_serv_sync() call from nfsd_create_serv(). - Removed inline from fs/nfsd/localio.c:nfs_stat_to_errno - Wrapped localio struct nfs_client members and related fs/nfs/client.c init code with #if IS_ENABLED(CONFIG_NFS_LOCALIO) - Requested a unique RPC program number from IANA but switched to using 0x20000002 until one is assigned. - Improved the Documentation and some code comments. Otherwise, not a lot of actual code changes. My git tree is here: https://git.kernel.org/pub/scm/linux/kernel/git/snitzer/linux.git/ This v6 is both branch nfs-localio-for-6.11 (always tracks latest) and nfs-localio-for-6.11.v6 Branches nfs-localio-for-6.11.v[12345] are also available. To see the changes from v5 to v6 please do: git remote add snitzer git://git.kernel.org/pub/scm/linux/kernel/git/snitzer/linux.git git remote update snitzer git diff snitzer/nfs-localio-for-6.11.v5 snitzer/nfs-localio-for-6.11.v6 All review and comments are welcome!
