Abstract
Described are techniques for processing data. A notification is sent from an application to a cache manager to invalidate any cache location storing data for a first logical address. Responsive to receiving the notification, first processing is performed by the cache manager comprising determining whether data for the first logical address is stored in a cache location; and if it is determined that data for the first logical address is stored in the cache location, designating the cache location as any of free and available for reuse. The foregoing processing for invalidation may also be performed to invalidate a set of cache locations for data from multiple logical addresses.
