2 kinds of locks - per-inode (->i_rwsem) and per-filesystem
6 always acquire the locks in order by increasing address.  We'll call
11 1) read access.  Locking rules: caller locks directory we are accessing.
17 3) object removal.  Locking rules: caller locks parent, finds victim,
18 locks victim and calls the method.  Locks are exclusive.
20 4) rename() that is _not_ cross-directory.  Locking rules: caller locks
25 Then call the method.  All locks are exclusive.

89 non-directory objects are not included in the set of contended locks.

108 means that cross-directory rename is taking locks out of order.  Due
