tracing: remove notrace from __kprobes annotation (fe832a3a) · Commits · 戴 / test

When ftrace had issues with NMIs, it was needed to annotate all the areas that kprobes had issues with notrace. Now that ftrace is NMI safe, the functions that limit ftrace from tracing are just a small few. Kprobes is too big of a set for ftrace not to trace. Remove the coupling. Signed-off-by:
