I want to know the call stack of a read() to a file which stored in NVMe SSD.

But strace can only tell the syscall.

I want a stack like:

...
blk_mq_submit_bio()
submit_bio()
...

Hoping for help.

Upd: Reopen.

This question should be reopened. The supposed duplicate question is asking how to get the stacktrace from _inside_ the kernel. This question is asking how to get the kernel's stacktrace _from userspace_. So, the linked question doesn't answer this question. Please reopen the question. – Sagar Aug 04 '21 at 17:22
