commit: 30373dc0c87ffef68d5628e77d56ffb1fa22e1ee From: Tim Gardner <[email protected]> Date: Thu, 12 Jan 2012 16:31:55 +0100 Subject: ecryptfs: Improve metadata read failure logging
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`.
