Linus,
This patchset removes the hard NGROUPS limit. It has been in use in a similar
form on our systems for some time.
There is a small change needed for glibc, and I will send that patch to the
glibc people if/when this gets pulled.
Unlike prior versions of this patch, I have changed qsort() to a simple
non-recursive sort. Several people indicated that this change would solve
their objections.
Lastly, this does not fixup all the architectures. I have other patchsets for
that, which need to be reviewed by arch maintainers.
Tim

<[email protected]> (02/11/11 1.855)
fix usage of NGROUPS in nfsd and svcauth
<[email protected]> (02/11/11 1.854)
Remove the limit of 32 groups. We now have a per-task, dynamic array of
groups, which is kept sorted and refcounted.
This ChangeSet incorporates all the core functionality. but does not fixup
all the incorrect usages of groups. That is in a seperate ChangeSet.
