Hi,

I have kcore and I want to get userspace backtrace from kcore. I looked at some macro but still this is just giving me kernel backtrace only. What I want is userspace backtrace.

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 ?
