Not your bug, but serialize() needs to be __always_inline.  Not sure what exactly
caused it to be uninlined, but this is the obvious new usage.

vmlinux.o: warning: objtool: __static_call_update_early+0x4e: call to serialize() leaves .noinstr.text section
vmlinux.o: warning: objtool: ct_work_flush+0x69: call to serialize() leaves .noinstr.text section
