[PATCH v2 7/9] fs/ext4: Make DAX mount option a tri-state

2020-05-14 Thread ira . weiny
From: Ira Weiny We add 'always', 'never', and 'inode' (default). '-o dax' continues to operate the same which is equivalent to 'always'. This new functionality is limited to ext4 only. Specifically we introduce a 2nd DAX mount flag EXT4_MOUNT2_DAX_NEVER and set it and EXT4_MOUNT_DAX_ALWAYS app
