Adding 'Analyzed-by' tag at the 2nd patch 2. Using a inline function instead #define at the 7th patch Let me know if the above should still be applied. 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 (6): 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 Documentation/admin-guide/kernel-parameters.txt | 3 +++ block/bio.c | 19 +++++-------------- block/genhd.c | 10 ++-------- include/linux/completion.h | 14 ++++++++++++++ include/linux/genhd.h | 24 ++++++++++++++++++++++-- include/linux/workqueue.h | 4 ++-- kernel/locking/lockdep.c | 23 +++++++++++++++++++++-- kernel/workqueue.c | 19 +++---------------- lib/Kconfig.debug | 19 +++++++++++++++++-- 9 files changed, 89 insertions(+), 46 deletions(-) -- 1.9.1 -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
