Abstract
Various systems and methods for inhibiting a modified block of data from being written to an underlying persistent storage device are disclosed. A cache is maintained by a file system and the cache is implemented to temporarily cache portions of application data for an application. The application data for the application is stored on the underlying persistent storage device. Metadata is accessed if it is detected that a block of data in the cache has been modified. The metadata indicates that the block of data is not needed for the integrity of the application. In response to the metadata, the modified block of data is inhibited from being written to the underlying persistent storage device.
