Tracepoint is a predefined hook point in the kernel, compared to Kprobe, it is more stable and has lower performance overhead, although compatibility is relatively poor, it is still worth trying By the way, we have also included the config definitions related to hook types in Kconfig, to enhance cleanliness Improve and merge types that do not require hooks Introducing the hook type prctl These patches is based on backslashxx/KernelSU#5 Co-authored-by: Cloud_Yun <1770669041@qq.com> Co-authored-by: Prslc <prslc113@gmail.com> Co-authored-by: ShirkNeko <109797057+ShirkNeko@users.noreply.github.com> Signed-off-by: ShirkNeko <109797057+ShirkNeko@users.noreply.github.com>
