The first two are trivial, short, and should not be an issue. The first two handle the printing of the set_ftrace_filter file correctly. The third is a bigger patch "108 lines changed" and is actually a clean up and fix. The difference is that the current logic to determine if a function should be enabled or not is incorrect. With different combinations of using set_ftrace_filter and set_ftrace_notrace, incorrect functions may be traced, or not traced. But this bug that the patch fixes is not a critical bug. It should not cause any stability problems with the kernel. The bug will only produce undesirable traces. But on the other hand, adding that last patch should not cause any stability issues as well. And it makes the complex function cleaner and more importantly, by coupling the ENABLED flag of the record with the enabling (or disabling) of the tracing of the function the record represents, makes the code more robust. The following patches are in: git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-2.6-trace.git branch: tip/urgent Steven Rostedt (3): ftrace: fix set_ftrace_filter ftrace: make filtered functions effective on setting ftrace: fix dyn ftrace filter selection ---- kernel/trace/ftrace.c | 113 +++++++++++++++++++++++------------------------- 1 files changed, 54 insertions(+), 59 deletions(-)
