From f5aed2c2a825618553b20e8a67109570489b40d7 Mon Sep 17 00:00:00 2001 From: Theodore Ts'o Date: Mon, 18 May 2015 13:18:47 -0400 Subject: ext4: clean up superblock encryption mode fields The superblock fields s_file_encryption_mode and s_dir_encryption_mode are vestigal, so remove them as a cleanup. While we're at it, allow file systems with both encryption and inline_data enabled at the same time to work correctly. We can't have encrypted inodes with inline data, but there's no reason to prohibit unencrypted inodes from using the inline data feature.
