Steven Rostedt (VMware) f61872bb58 bootconfig: Use parse_args() to find bootconfig and '--' ... The current implementation does a naive search of "bootconfig" on the kernel command line. But this could find "bootconfig" that is part of another option in quotes (although highly unlikely). But it also needs to find '--' on the kernel command line to know if it should append a '--' or not when a bootconfig in the initrd file has an "init" section. The check uses the naive strstr() to find to see if it exists. But this can return a false positive if it exists in an option and then the "init" section in the initrd will not be appended properly. Using parse_args() to find both of these will solve both of these problems.
