[PATCH] btrfs-progs: add supported attr flags to btrfs(5)
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.
