View File

@ -13,11 +13,16 @@ the wildcard key may be found during lookup but the map it blongs to
isn't checked so it can be incorrectly returned instead of a matching
entry in a subsequent included map.
Another problem case is when there's a wildcard match and a cache prune
occurs while the mount is being done. In this case the matched cache
entry that has been added is seen as stale and removed along with the
mount point directory during the prune leading to a mount fail.
