From ee1d6d37b6b884383b501089be93ce94f2153028 Mon Sep 17 00:00:00 2001 From: Amir Goldstein Date: Thu, 11 May 2017 16:42:26 +0300 Subject: ovl: mark upper dir with type origin entries "impure" When moving a merge dir or non-dir with copy up origin into a non-merge upper dir (a.k.a pure upper dir), we are marking the target parent dir "impure". ovl_iterate() iterates pure upper dirs directly, because there is no need to filter out whiteouts and merge dir content with lower dir. But for the case of an "impure" upper dir, ovl_iterate() will not be able to iterate the real upper dir directly, because it will need to lookup the origin inode and use it to fill d_ino.
