From f941866fc4a8ad0d0b861cc2dbffa06a9f5e8963 Mon Sep 17 00:00:00 2001 From: Amir Goldstein Date: Fri, 19 Jan 2018 21:33:44 +0200 Subject: ovl: decode lower non-dir file handles Decoding a lower non-dir file handle is done by decoding the lower dentry from underlying lower fs, finding or allocating an overlay inode that is hashed by the real lower inode and instantiating an overlay dentry with that inode.
