I forgot to mention that Steven is working on a system call for dynamic
linkers to register .sframe for .text in dynamic libraries (DSOs), that
is supposed to replace the last test-patch of this series. Feedback
on that is much appreciated as well:
[RFC][PATCH] unwind: Add stacktrace_setup system call
