Hi, There seems to be consensus that these changes worthwhile and extensively iterated on. I really appreciate the coordinated development and review to this point. I'd very much like these changes to land upstream as-is (unless review teases out some show-stopper). These changes have been tested fairly extensively (via xfstests) at this point. Can we noew please provide formal review tags and merge these changes through the NFS client tree for 6.11? Changes since v10: - Now that XFS will _not_ be patched with "xfs: enable WQ_MEM_RECLAIM on m_sync_workqueue", reintroduce "nfs/localio: use dedicated workqueues for filesystem read and write" (patch 18). Also fixed it so that it passes xfstests generic/355. FYI: - I do not intend to rebase this series ontop of NeilBrown's partial exploration of simplifying away the need for a "fake" svc_rqst (noble goals and happy to help those changes land upstream as an incremental improvement): https://marc.info/?l=linux-nfs&m=171980269529965&w=2 - In addition, tweaks to use nfsd_file_acquire_gc() instead of nfsd_file_acquire() aren't a priority. Each incremental change comes with it the potential for regression and we need to lock-down and stop churning. Happy to explore as incremental improvement and optimization. All review and comments are welcome!
