Kernel symbol naming rules

March 24, 2016

      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,
