Revision f3a1568582cc207663a4d5e37da790334372855b authored by Amir Goldstein on 24 May 2017, 12:29:33 UTC, committed by Miklos Szeredi on 29 May 2017, 09:48:00 UTC
An upper dir is marked "impure" to let ovl_iterate() know that this directory may contain non pure upper entries whose d_ino may need to be read from the origin inode. We already mark a non-merge dir "impure" when moving a non-pure child entry inside it, to let ovl_iterate() know not to iterate the non-merge dir directly. Mark also a merge dir "impure" when moving a non-pure child entry inside it and when copying up a child entry inside it. This can be used to optimize ovl_iterate() to perform a "pure merge" of upper and lower directories, merging the content of the directories, without having to read d_ino from origin inodes.
