Shouldn't we check the value of the extended attrs too?

No need to do this anymore; _begin_fstest takes care of this now.

"attr16" is seventeen bytes long.

This is 17k long...

...and this 136K long?
I'm curious, what are the contents of user.attr_name8?
OH, I see, attr clamps the value length to 64k, so I guess the oversize
