- Use a prefix "(gendisk_completion)" instead of "(complete)" for gendisk's map
- Provide empty lockdep_map structure for !CONFIG_LOCKDEP
- Remove #ifdef in this series as much as possible
- Use canocical variable names in all_disk_node() macro

Changes from v3
- Exclude a patch removing white space
- Enhance commit messages as Ingo suggested
- Re-design patches adding a boot param and a Kconfig allowing unwind
- Simplify a patch assigning lock classes to genhds as Ingo suggested
- Add proper tags in commit messages e.g. reported-by and analyzed-by

Changes from v2
- Combine 2 serises, fixing false positives and enhance performance
- Add Christoph Hellwig's patch simplifying submit_bio_wait() code

- Rename init_completion_with_map() to init_completion_map()

Changes from v1

- Fix commit message writing out CONFIG_ variable
- Introduce a new kernel parameter, crossrelease_fullstack
- Replace the number with the output of *perf*
- Separate a patch removing white space
