It will make setgroups16() return > -ENOMEM, which seems inappropriate. [...snip...] How is the .config valid, given that UID16 *depends* on MULTIUSER? This shouldn't be possible, and I know Iulia specifically addressed this case by adding that dependency (without which this *exact* error would occur). Is something doing "select UID16" and missing its dependency? I don't see any selects for UID16 anywhere in-tree. - Josh Triplett -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
