In this version I just added Fixes tags so that it makes clear which release should be fixed. Recently I got 2 issues reported by Andreas, see https://www.mail-archive.com/linux-kernel@vger.kernel.org/msg1899098.html One issue is already fixed by Andreas (Thanks!) but $comm handling issue still exists on uprobe event. [1/3] fixes it. And I found other issues around that, [2/3] is just a trivial cleanup, [3/3] fixes $comm type issue which occurs not only uprobe events but also on kprobe events. Anyway, after this series applied, $comm must be "string" type and not be an array. Thank you, --- Masami Hiramatsu (3): tracing: uprobes: Re-enable $comm support for uprobe events tracing: probeevent: Do not accumulate on ret variable tracing: probeevent: Fix to make the type of $comm string kernel/trace/trace_probe.c | 13 +++++++------ kernel/trace/trace_probe_tmpl.h | 2 +- kernel/trace/trace_uprobe.c | 15 +++++++++++++-- 3 files changed, 21 insertions(+), 9 deletions(-) -- Masami Hiramatsu (Linaro)
