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: https://github.com/dynup/kpatch/issues/493 Signed-off-by: Chris J Arges <chris.j.arges@canonical.com> Reviewed-by: Petr Mladek <pmladek@suse.com> Acked-by: Josh Poimboeuf <jpoimboe@redhat.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
