Abstract

Processing restrictions of a computing environment are filtered and blocked, in certain circumstances, such that processing continues despite the restrictions. One restriction includes an indication that fetching of storage keys is prohibited, in response to a buffer miss. When a processing unit of the computing environment is met with this restriction, it performs a comparison of addresses, which indicates whether the fetching can continue. If fetching can continue, the restriction is ignored.
