Systems, methods, and computer program products to perform an operation comprising receiving a policy document specifying a plurality of criteria, identifying, in a segment of unstructured text in the policy document, a criteria delimiter, creating a first portion and a second portion of the segment of unstructured text, wherein the first and second portions are created based on the criteria delimiter, wherein the first and second portions comprise a first criterion and a second criterion, respectively, and responsive to identifying an anaphora in the second portion of the segment of unstructured text that is related to a term in the first portion of the segment of unstructured text, combining the first criterion and the second criterion into a composite criterion.

Criteria modification to improve analysis

A data structure used by an operating system to refer to a filesystem object includes information that permits the structure to be associated with filesystem objects having different filesystem implementations. The data structure is associated with a filesystem object that is linked into different directories that have different filesystem implementations. Therefore, the data structure includes respective information within it about each different link. As a result, a filesystem object, such as a directory, having one filesystem implementation may be created in or moved to another directory having a different filesystem implementation; or, a file may be linked in multiple directories having different implementations.

Method for supporting multiple filesystem implementations

A filesystem conversion process converts a filesystem from one implementation type to another type while the filesystem remains active and fully accessible. The conversion process builds a list of directories in the filesystem that are of the old filesystem type and then converts each directory until the entire filesystem is converted. Instead of the filesystem being shutdown to perform the conversion, the conversion process may run as a background thread that does not interfere with normal filesystem operations.

Method of converting a filesystem while the filesystem remains in an active state

Embodiments of the present invention are generally directed to a method, apparatus and system for journaling an object in a file system of a computer. In one aspect, a request to make a change on the object is received. In response, a journal entry containing a set of information regarding the change is generated. The journal entry is then stored to a journal. A determination is made as to whether the object contains an indicator indicating to a journal file system to bypass storing the change to the object. If so, the journal file system bypasses storing the change to the object if the object contains the indicator.

Method for efficient recording and management of data changes to an object

A system and method for automatic journaling of objects in a computer file system. A journal directory operation is caused when a new or existing object to be linked into a directory if the directory has an attribute indicating automatic journaling status. An operating system synchronization lock is acquired before the object is journaled to preserve the object from changes by the operating system, and held in place until after journaling has started.

Continuous journaling of objects within a hierarchical directory tree
