For now, wait_for_completion() / complete() works with lockdep, add
lock_page() / unlock_page() and its family to lockdep support.
Changes from v1
- Move lockdep_map_cross outside of page_ext to make it flexible
- Prevent allocating lockdep_map per page by default
- Add a boot parameter allowing the allocation for debugging
Byungchul Park (4):
lockdep: Apply crossrelease to PG_locked locks
lockdep: Apply lock_acquire(release) on __Set(__Clear)PageLocked
lockdep: Move data of CONFIG_LOCKDEP_PAGELOCK from page to page_ext
lockdep: Add a boot parameter enabling to track page locks using
lockdep and disable it by default
