Introduce write_threads, write_version and write_ports netlink commands similar to the ones available through the procfs. Changes since v3: - drop write_maxconn and write_maxblksize for the moment - add write_version and write_ports commands Changes since v2: - use u32 to store nthreads in nfsd_nl_threads_set_doit - rename server-attr in control-plane in nfsd.yaml specs Changes since v1: - remove write_v4_end_grace command - add write_maxblksize and write_maxconn netlink commands This patch can be tested with user-space tool reported below: https://github.com/LorenzoBianconi/nfsd-netlink.git This series is based on the commit below available in net-next tree commit e0fadcffdd172d3a762cb3d0e2e185b8198532d9 Author: Jakub Kicinski <kuba@xxxxxxxxxx> Date: Fri Oct 6 06:50:32 2023 -0700 tools: ynl-gen: handle do ops with no input attrs The code supports dumps with no input attributes currently thru a combination of special-casing and luck. Clean up the handling of ops with no inputs. Create empty Structs, and skip printing of empty types. This makes dos with no inputs work.
