- cleanups:
. kprobes: Fixes typo in kprobes samples.
. tracing/eprobes: Remove 'break' after return.
- kretprobe/fprobe performance improvements:
. lib: Introduce new `objpool`, which is a high performance lockless
object queue. This uses per-cpu ring array to allocate/release
objects from the pre-allocated object pool. Since the index of ring
array is a 32bit sequential counter, we can retry to push/pop the
object pointer from the ring without lock (as seq-lock does).
. lib: Add an objpool test module to test the functionality and
evaluate the performance under some circumstances.
. kprobes/fprobe: Improve kretprobe and rethook scalability
performance with objpool.
This improves both legacy kretprobe and fprobe exit handler (which
is based on rethook) to be scalable on SMP systems. Even with
8-threads parallel test, it shows a great scalability improvement.
. Remove unneeded freelist.h which is replaced by objpool.
. objpool: Add maintainers entry for the objpool.
. objpool: Fix to remove unused include header lines.
