I have kcore and I want to get userspace backtrace from kcore. I looked at
some macro <https://www.kernel.org/doc/Documentation/kdump/gdbmacros.txt> but
still this is just giving me kernel backtrace only. What I want is
Good news is I have pointer to task_struct.
task_struct->thread->sp (Kernel stack pointer)
task_struct->thread->usersp (user stack pointer) but this is junk
My question is how to get userspace backtrace (or stack pointer) from kcore
or task_struct ?
