Subject: [PATCH v2 0/4] lockdep/crossrelease: Apply crossrelease to page locks
Date: Mon,  4 Dec 2017 14:16:19 +0900	[thread overview]
Message-ID: <1512364583-26070-1-git-send-email-byungchul.park@lge.com> (raw)

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
