[PATCH] keys: sort out key quota system
Add the ability for key creation to overrun the user's quota in some
circumstances - notably when a session keyring is created and assigned to a
process that didn't previously have one.
This means it's still possible to log in, should PAM require the creation of a
new session keyring, and fix an overburdened key quota.
