Hi Steven Rostedt, Li Zefan, This fixes an issue with macro expansion introduced in commit 7d536cb3f (tracing/events: record the size of dynamic arrays).
I split it in 3 patches, the first fixes a bug, the second improves the code to evaluate the expression only once and the third refactors an u32 holding two pieces of data in lower/higher 16 bits into a struct to make the code cleaner. I split them this way since I expect the first two to be more straightforward while the third one might generate some discussion. I'd be happy to squash them into a single one if you'd prefer that. Cheers, Filipe Filipe Brandenburger (3): tracing: correctly expand len expressions from __dynamic_array macro tracing: evaluate len expression only once in __dynamic_array macro tracing: introduce a trace_data_offset struct to store array size include/linux/ftrace_event.h | 5 +++++ include/trace/ftrace.h | 26 ++++++++++++++------------ kernel/trace/trace_events_filter.c | 13 ++++++++++--- 3 files changed, 29 insertions(+), 15 deletions(-) -- 1.9.0.279.gdc9e3eb -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
