Hi, Ingo

Do you have any objections against these patches?
[PATCH tip/tracing/markers] markers: simplify marker_set_format()
[PATCH tip/tracing/markers] markers: remove exported symbol marker_probe_cb_noarg()
[PATCH tip/tracing/markers] markers: let marker_table be close to its comments

My new patch are being made on the top of these patches.
new patch:
[PATCH tip/tracing/markers] markers: new callbacks manager
new patch remove a lot code and speed up critical region
and not change any APIs.

new patch change too much code, so I have to wait until all known
patches(which can be applied) have been applied.

Thanks, Lai
