All those are handled in the rseq selftests and in librseq. Why duplicate all

Therefore, the algorithm proposed has O(n*log(n)) complexity with GNU
coreutils' sort compared to the prior O(n^2) complexity. Moreover, the
constant time required for each list entry is much less because sorting
is done within a single execution of sort(1) rather than requiring

I notice that the same quadratic sorting is done for other supported
OSes, so I suspect similar gains can be obtained there, but I limit the

You can query it with modinfo /lib/modules/$(uname -r)/extra/lttng-tracer.ko

module locks, so the tracer can dump this information on trace start
and module load.
Use-case (b) is very similar to what is done for the kernel tracepoints. Based

populates
a hash table for use-case (a) should be easy enough.

Mathieu
