cred: Fix RCU warnings in override/revert_creds

2025-03-02T11:57:37+00:00

Fix RCU warnings in override_creds and revert_creds by turning
the RCU pointer into a normal pointer using rcu_replace_pointer.

These warnings were previously private to the cred code, but due
to the move into the header file they are now polluting unrelated
subsystems.

cred: return old creds from revert_creds_light()

2024-12-02T10:25:08+00:00

So we can easily convert revert_creds() callers over to drop the
reference count explicitly.

cred: Add a light version of override/revert_creds()

2024-11-11T09:45:04+00:00

Add a light version of override/revert_creds(), this should only be
used when the credentials in question will outlive the critical
section and the critical section doesn't change the ->usage of the
credentials.
