            Bug ID: 9946
           Summary: mv is corrupting files on aufs filesystem (e.g. used
                    by open-source docker V17.03)
           Product: Busybox
           Version: 1.22.x
          Hardware: All
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P5
         Component: Other
          Assignee: unassigned at busybox.net
          Reporter: steffen.guertler at bosch-si.com
                CC: busybox-cvs at busybox.net
  Target Milestone: ---

if mv several subdirectories to another directory mv is not copying the correct
content but several files have content of other files.

Debugging this behavior with strace, I could see that the rename() call failed
with EXDEV and the underlying aufs filesystem changing (and reusing) inode
numbers during the whole process. This conflicts with the inode_hash table.

In the trace output below, "target/d2/c" will have the content of
"target/d1/image4.bmp" and "target/d2/d" the content of "target/d1/image3.bmp"
instead of there original content:
