From: Steven Rostedt Impact: fix to unsigned compared to less than zero Roel Kluin pointed out that there is a compare of an unsigned number to less than zero. A previous clean up had the unsigned index set to -1 for certain cases, but never converted it to signed. Frederic Weisbecker noticed that another index is used to compare the above index to and it also needs to be converted to signed. [ Converted ftrace_page->index to int from unsigned long as Andrew Morton pointed out that there's no need for it to stay a long. ] Reported-by: Roel Kluin Reported-by: Frederic Weisbecker Signed-off-by: Steven Rostedt --- kernel/trace/ftrace.c | 4 ++-- 1 files changed, 2 insertions(+), 2 deletions(-) diff --git a/kernel/trace/ftrace.c b/kernel/trace/ftrace.c index 2f32969..9e54a6c 100644 --- a/kernel/trace/ftrace.c +++ b/kernel/trace/ftrace.c @@ -289,7 +289,7 @@ static DEFINE_MUTEX(ftrace_regex_lock); struct ftrace_page { struct ftrace_page *next; - unsigned long index; + int index; struct dyn_ftrace records[]; }; @@ -786,7 +786,7 @@ enum { struct ftrace_iterator { struct ftrace_page *pg; - unsigned idx; + int idx; unsigned flags; unsigned char buffer[FTRACE_BUFF_MAX+1]; unsigned buffer_idx; -- 1.5.6.5 -- -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
