We can go on looking at each of the patches to see which ones can be cherry picked, i.e. the ones that are fixes and not related to the work you're doing, like: commit 244c87b15b124914827f3ce28d8e70c8d147c9d0 Author: Adrian Hunter <[email protected]> Date: Wed Jun 11 09:33:17 2014 +0300 perf tools: Fix the value used for unknown pids The value used for unknown pids cannot be zero because that is used by the "idle" task. Use -1 instead. Also handle the unknown pid case when creating map groups. Note that, threads with an unknown pid should not occur because fork (or synthesized) events precede the thread's existence. Signed-off-by: Adrian Hunter <[email protected]> But then one by one they need to be reviewed to check if the changes were made to the whole tools/perf/ tree and if perhaps something new came along since you changed some assumption, like 0 meaning unknown thread, in the above patch: [acme@ssdandy linux]$ find tools -name "*.[ch]" | xargs grep machine__findnew_thread | grep 0 tools/perf/util/session.c: thread = machine__findnew_thread(&session->machines.host, 0, 0); tools/perf/tests/thread-mg-share.c: leader = machine__findnew_thread(machine, 0, 0); tools/perf/tests/thread-mg-share.c: t1 = machine__findnew_thread(machine, 0, 1); tools/perf/tests/thread-mg-share.c: t2 = machine__findnew_thread(machine, 0, 2); tools/perf/tests/thread-mg-share.c: t3 = machine__findnew_thread(machine, 0, 3); [acme@ssdandy linux]$ So I think that one way to reduce the size of that branch is to do just that: start fresh from tip/perf/core, and go cherry picking those patches, making sure that they take into account the whole current tools/perf/ tree, then ask for this patch to be pulled. You could then rebase the old branch on top of the resulting branch once it is merged upstream, rinse repeat. - Arnaldo -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
