The persistent keyring is a keyring used to anchor keys on behalf of a user.
Each UID the kernel deals with has its own persistent keyring that
is shared between all threads owned by that UID.
The persistent keyring has a name (description) of the form
.I _persistent.<UID>
where
.I <UID>
is the user ID of the corresponding user.
The persistent keyring may not be accessed directly,
even by processes with the appropriate UID.
