Hi, This v5 is rebased on Chuck's nfsd-next (only required one adjustment in patch 15 to account for new code that dereferences nn->nfsd_serv). Only other change is patch 19 to add Documentation/filesystems/nfs/localio.rst My git tree is here: https://git.kernel.org/pub/scm/linux/kernel/git/snitzer/linux.git/ This v5 is both branch nfs-localio-for-6.11 (always tracks latest) and nfs-localio-for-6.11.v5 Branches nfs-localio-for-6.11.v[1234] are also available. To see the changes from v4 to v5 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.v4 snitzer/nfs-localio-for-6.11.v5 [NOTE: there will be noise due to nfsd-next causing the base kernel to move from v6.10-rc2 to v6.10-rc3] All review and comments are welcome!
