|
* @description A re-created path must NOT show up twice in readdir. The reported
|
||
|
|
* defect (memory-vm) was readdir serving DUPLICATE entries for re-created paths,
|
||
|
|
* rooted in a delete that left a ghost (partial removal) whose next delete read
|
||
|
|
* null metadata and skipped unposting the stale Contains edge. With full-removal
|
||
|
|
* deletes there is no ghost, so the edge is always unposted and the path appears
|
||
|
|
* exactly once after any number of delete→recreate cycles.
