Hi,

the function crcmp() in kern_prot.c still contains a big FIXME comment, 
indicating that the comparison of group lists may fail even if the group 
lists are equivalent. Christos has added a function grsortu() that sorts 
the group lists when they are set using setgroups().

How can we assure that every group list that is used in the kernel is 
appropriately sorted? Some kind of check_grsortu() that prints a warning 
everytime an unsorted group list is found? If this is reasonable, where 
should that function be called?

I don't know the whole kernel, but this should be fixed, maybe even 
before the 3.0 release.
