The export was added to let drm control pr_debugs, as part of using them to avoid drm_debug_enabled overheads. But following patches implement the drm.debug interface, and adapt drm to just use it, so nobody will never need the export. This also drops the CONFIG_DYNAMIC_DEBUG=N stub-func, and its pr_warn(), which I avoided in 2012, then added in 2020 :-/ Fixes: a2d375eda771 ("dyndbg: refine export, rename to dynamic_debug_exec_queries()") Fixes: 4c0d77828d4f ("dyndbg: export ddebug_exec_queries") Signed-off-by: Jim Cromie --- include/linux/dynamic_debug.h | 8 -------- lib/dynamic_debug.c | 29 ----------------------------- 2 files changed, 37 deletions(-) diff --git a/include/linux/dynamic_debug.h b/include/linux/dynamic_debug.h index f30b01aa9fa4..dd20e825c36f 100644 --- a/include/linux/dynamic_debug.h +++ b/include/linux/dynamic_debug.h @@ -55,9 +55,6 @@ struct _ddebug { #if defined(CONFIG_DYNAMIC_DEBUG_CORE) -/* exported for module authors to exercise >control */ -int dynamic_debug_exec_queries(const char *query, const char *modname); - int ddebug_add_module(struct _ddebug *tab, unsigned int n, const char *modname); extern int ddebug_remove_module(const char *mod_name); @@ -221,11 +218,6 @@ static inline int ddebug_dyndbg_module_param_cb(char *param, char *val, rowsize, groupsize, buf, len, ascii); \ } while (0) -static inline int dynamic_debug_exec_queries(const char *query, const char *modname) -{ - pr_warn("kernel not built with CONFIG_DYNAMIC_DEBUG_CORE\n"); - return 0; -} #endif /* !CONFIG_DYNAMIC_DEBUG_CORE */ diff --git a/lib/dynamic_debug.c b/lib/dynamic_debug.c index ca2a28f1d51c..cdc0b03b1148 100644 --- a/lib/dynamic_debug.c +++ b/lib/dynamic_debug.c @@ -555,35 +555,6 @@ static int ddebug_exec_queries(char *query, const char *modname) return nfound; } -/** - * dynamic_debug_exec_queries - select and change dynamic-debug prints - * @query: query-string described in admin-guide/dynamic-debug-howto - * @modname: string containing module name, usually &module.mod_name - * - * This uses the >/proc/dynamic_debug/control reader, allowing module - * authors to modify their dynamic-debug callsites.
