Cleanup, compatibilityv5.0-pre7
- Use is_vmalloc_addr when freeing vmalloc or kmalloc-ed areas. Thus we can get rid of a flag and simplify some functions. - When checking "same" sets, ignore hash size, because resizing changes it. - 2.6.35 compatibility added. - Discuss backward/forward compatibilities in the README file.
