Subject: [PATCH v5 0/9] cross-release: Enhence performance and fix false positives

Changes from v4
- Use a prefix "(completion)" instead of "(complete)" for completions
- Use a prefix "(wq_completion)" instead of "(complete)" for workqueue's map
- Use a prefix "(work_completion)" instead of "(complete)" for work's map
- 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
- Add 2 more 'init with lockdep map' macros for completionm
- Rename init_completion_with_map() to init_completion_map()

Changes from v1
- Fix kconfig description as Ingo suggested
- 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

Byungchul Park (8):
  locking/lockdep: Provide empty lockdep_map structure for
    !CONFIG_LOCKDEP
  completion: Change the prefix of lock name for completion variable
  locking/lockdep: Add a boot parameter allowing unwind in cross-release
    and disable it by default
  locking/lockdep: Remove the BROKEN flag from
    CONFIG_LOCKDEP_CROSSRELEASE and CONFIG_LOCKDEP_COMPLETIONS
  locking/lockdep: Introduce
    CONFIG_BOOTPARAM_LOCKDEP_CROSSRELEASE_FULLSTACK
  completion: Add support for initializing completion with lockdep_map
  workqueue: Remove unnecessary acquisitions wrt workqueue flush
  block: Assign a lock_class per gendisk used for wait_for_completion()

Christoph Hellwig (1):
  block: use DECLARE_COMPLETION_ONSTACK in submit_bio_wait
