JFFS2 is the second generation of the Journalling Flash File System
for use on diskless embedded devices. It provides improved wear
messages at debug level 1 while the misbehaviour was occurring.

- extended attributes beginning with the user namespace prefix
- to SMB/CIFS EAs. EAs are stored on Windows servers without the
- user namespace prefix, but their names are seen by Linux cifs clients
