Fixes this error: dynamic_debug:ddebug_parse_query: last-line:0 < 1st-line:1 dynamic_debug:ddebug_exec_query: query parse failed Link: http://lkml.kernel.org/r/10a6a101-e2be-209f-1f41-54637824788e@infradead.org Signed-off-by: Randy Dunlap Acked-by: Jason Baron Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds Signed-off-by: Sasha Levin Signed-off-by: Greg Kroah-Hartman --- diff --git a/lib/dynamic_debug.c b/lib/dynamic_debug.c index da796e2dc4f5..c7c96bc7654a 100644 --- a/lib/dynamic_debug.c +++ b/lib/dynamic_debug.c @@ -360,6 +360,10 @@ static int ddebug_parse_query(char *words[], int nwords, if (parse_lineno(last, &query->last_lineno) < 0) return -EINVAL; + /* special case for last lineno not specified */ + if (query->last_lineno == 0) + query->last_lineno = UINT_MAX; + if (query->last_lineno < query->first_lineno) { pr_err("last-line:%d < 1st-line:%d\n", query->last_lineno,
