livepatch: function,sympos scheme in livepatch sysfs directory
The following directory structure will allow for cases when the same
function name exists in a single object.
/sys/kernel/livepatch/<patch>/<object>/<function,sympos>
The sympos number corresponds to the nth occurrence of the symbol name in
kallsyms for the patched object.
An example of patching multiple symbols can be found here:
