The chattr(1) manpage suffers from the same problems mount(1)
had: many options listed, not kept up to date for various
filesystems.
I've submitted a manpage update for chattr(1) which says to
refer to filesystem-specific manpages for supported attributes;
this patch updates btrfs(5) to list the attributes supported
by btrfs.
