Just had this myself compiling some new code - it disappeared when I 
retried the compile. Maybe a make clean would help, there might be 
mismatching code builds.

It should show up in attr_get_fd, will check that. The attribute is 
not copied to the process, so there is none. Instead, the value 
returned is taken from the task struct - the place has changed in 2.6 
pax recently, I will check that, too.
