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.

v2:
* For patch 3, avoid to call lockdep_unlock() twice after counting deps.
  Please see https://lkml.org/lkml/2021/6/17/741. 

Xiongwei Song (3):
  locking/lockdep: Unlikely bfs_error() inside
  locking/lockdep: Unlikely conditons about BFS_RMATCH
  locking/lockdep: Print possible warning after counting deps
