Date: Thu, 17 Jun 2021 22:28:25 +0800 [thread overview]
Message-ID: <20210617142828.346111-1-sxwjean@me.com> (raw)
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
