Boqun Feng 93cc59d8d0 locking/lockdep: Fix the dep path printing for backwards BFS ... [ Upstream commit 69c7a5fb2482636f525f016c8333fdb9111ecb9d ] We use the same code to print backwards lock dependency path as the forwards lock dependency path, and this could result into incorrect printing because for a backwards lock_list ->trace is not the call trace where the lock of ->class is acquired. Fix this by introducing a separate function on printing the backwards dependency path. Also add a few comments about the printing while we are at it.
