According to the comment from commit bc21b478 this won't work. Note, it does not work with the iterator "trace" file, since it requires the use of consuming the page from the ring buffer to determine how many events were lost, which the iterator does not do. I'm not sure the attached fix (2/2) is on the right place, but stops the LOST EVENTS display for iterator "trace" file. I also added option to control the LOST EVENTS display (1/2) if needed. attached patches: - 1/2 - adding lost-events option - 2/2 - supress lost events message for iterator "trace" wbr, jirka --- kernel/trace/trace.c | 24 ++++++++++++++---------- kernel/trace/trace.h | 1 + 2 files changed, 15 insertions(+), 10 deletions(-)
