Subject: [PATCH 0/3] some improvements for lockdep

Unlikely the checks of return values of graph walk will improve the
performance to some degree, patch 1 and patch 2 are for this.

The patch 3 will print a warning after counting lock deps when hitting
bfs errors.

Xiongwei Song (3):
  locking/lockdep: unlikely bfs_error function
  locking/lockdep: unlikely conditons about BFS_RMATCH
  locking/lockdep: print possible warning after counting deps
