hi,
Is there any way to get the function address by only knowing the function Name

See "kallsyms_lookup_name" in include/linux/kallsyms.h (implemented in kernel/kallsyms.c).

Beware:

- CONFIG_KALLSYMS might be undefined. In that case it always returns 0

- the function returns the address of *any* known symbol, not just functions (this can be easily improved to also return the symbol type)

- the function is extremely inefficient, as it does a linear search over all the symbols. kallsyms is optimized to work the other way around: get the name from the address.
