From 9b9f40e785724a265fb6027216fb2bd1e97894f7 Mon Sep 17 00:00:00 2001 From: Tim Gardner Date: Thu, 12 Jan 2012 16:31:55 +0100 Subject: ecryptfs: Improve metadata read failure logging commit 30373dc0c87ffef68d5628e77d56ffb1fa22e1ee upstream. Print inode on metadata read failure. The only real way of dealing with metadata read failures is to delete the underlying file system file. Having the inode allows one to 'find . -inum INODE`.
