(procfs_derived_probe::emit_module_decls): Include procfs-probes.c, which is where the definition of struct stap_procfs_probe exists. Update generated routines to read/write procfs data. (procfs_derived_probe_group::emit_module_init): Pass file_operations argument to _stp_create_procfs(). Initialize mutex. (procfs_var_expanding_visitor::visit_target_symbol): Update generated code. ----------------------------------------------------------------------- Summary of changes: runtime/procfs-probes.c | 204 +++++++++++++++++++++++++++++++++++++++++++++++ runtime/procfs.c | 15 +++- tapset-procfs.cxx | 114 ++++++++++++--------------- 3 files changed, 265 insertions(+), 68 deletions(-) create mode 100644 runtime/procfs-probes.c hooks/post-receive -- systemtap: system-wide probe/trace tool
