[PATCH] xfsprogs: add supported file attributes to xfs.5 manpage

[Eric Sandeen]

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 xfs(5) to list the attributes supported
by xfs.
