Kernel symbol naming rules

Kernel symbol naming rules

[Wenda Ni]

Hi all,

When doing insmod, we find our function named "rxe_mem_alloc" is renamed as
"rxe_mem_alloc.isra.2" in kernel symbol table @ /proc/kallsyms

 I am curious why the kernel appends ".isra.2" to the original function.
Why this happens? What is this for?

Thank you for sharing your thoughts.


Cheers,

Wenda Ni, Ph.D.

This is not kernel specific, rather it comes from the compiler, the
following stackoverflow answer puts it rather nicely:
