Changes since v3: - introduce rq_status_counter in order to detect if the RPC request is pending and RPC info are stable - rely on __svc_print_addr to dump IP info Changes since v2: - minor changes in nfsd_rpc_status_show output Changes since v1: - rework nfsd_rpc_status_show output Changes since RFCv1: - riduce time holding nfsd_mutex bumping svc_serv refcoung in nfsd_rpc_status_open() - dump rqstp->rq_stime - add missing kdoc for nfsd_rpc_status_open() Link: https://bugzilla.linux-nfs.org/show_bug.cgi?id=366 Lorenzo Bianconi (2): SUNRPC: add verbose parameter to __svc_print_addr() NFSD: add rpc_status entry in nfsd debug filesystem fs/nfsd/nfs4proc.c | 4 +- fs/nfsd/nfsctl.c | 10 +++ fs/nfsd/nfsd.h | 2 + fs/nfsd/nfssvc.c | 122 ++++++++++++++++++++++++++++++++ include/linux/sunrpc/svc.h | 1 + include/linux/sunrpc/svc_xprt.h | 12 ++-- net/sunrpc/svc.c | 2 +- net/sunrpc/svc_xprt.c | 2 +- 8 files changed, 144 insertions(+), 11 deletions(-)
