This patchset first attempts to detangle the pooled/non-pooled service handling in the sunrpc layer, unifies the codepaths that start the pooled vs. non-pooled nfsd, and then wires up the new netlink threads interface to allow you to start a pooled server by specifying an array of thread counts. Signed-off-by: Jeff Layton --- Changes in v2: - add new pool-mode set/get netlink calls --- Jeff Layton (5): sunrpc: fix up the special handling of sv_nrpools == 1 nfsd: make nfsd_svc call nfsd_set_nrthreads nfsd: allow passing in array of thread counts via netlink sunrpc: refactor pool_mode setting code nfsd: new netlink ops to get/set server pool_mode Documentation/netlink/specs/nfsd.yaml | 27 +++++++++ fs/nfsd/netlink.c | 17 ++++++ fs/nfsd/netlink.h | 2 + fs/nfsd/nfsctl.c | 102 +++++++++++++++++++++++++++++----- fs/nfsd/nfsd.h | 3 +- fs/nfsd/nfssvc.c | 30 +++++----- include/linux/sunrpc/svc.h | 3 + include/uapi/linux/nfsd_netlink.h | 10 ++++ net/sunrpc/svc.c | 102 +++++++++++++++++++++------------- 9 files changed, 225 insertions(+), 71 deletions(-) --- base-commit: fec4124bac55ad92c47585fe537e646fe108b8fa change-id: 20240604-nfsd-next-b04c0d2d89a9 Best regards,
