| Description |
|
mdd_linkea_update_child_internal() uses new target FID to find appropriate item in LinkEA. obviously it fails leaving LinkEA with a stale item. subsequent migration of that file breaks the filesystem as correct direntry can't be found: actual direntry in the directory(ies) becomes invalid, etc. |
