Abstract: A file system uses a B-tree data structure to organize file data. The file system may maintain an index node (mode) representing a file and having entries that map to extents of the file. When the file system detects an index node, through updates, has exceeded a threshold number of extents, the file system converts the file to a copy-on-write (COW) B-tree data structure containing the entries representing the extents of the file. To clone the file, the file system uses copies of the index node and the root node of the COW B-tree data structure.

Abstract: In a map data processing device for a vehicle, a map database has first map data of a road on which the vehicle travels. A map data computing module computes second map data of the road based on a surrounding environment and a traveling state of the vehicle. An update data computing module computes update data for updating the map database, based on a reliability of the second map data. An update determining module then compares the first map data with the update data. When both disagree with each other, the update determining module determines whether to update first map data with the update data, based on a frequency of discrepancy and the reliability. A data processing module executes a processing of updating the map database in accordance with a determination result by the update determining module.

Abstract: A precompiled form of information derived from CIL metadata is created in a compact type layout (CTL) format. Information in CTL format for each data type in a program can be represented as a contiguous byte stream. Information that is irrelevant to decisions concerning layout of a data type in memory can be suppressed. information that is irrelevant to creation of virtual machine data structures can be suppressed. The information in CTL format may reference types, methods, and fields by CIL metadata token. Virtual override information such as, for example, a logical virtual table layout, can be pre-computed. Interface implementation information can be pre-computed. A decoder can generate data structures used in generation of an executable from the CTL formatted data.

Two documents may be considered to be near-duplicates if any one of their fingerprints match.

Abstract: Disclosed is a method to synchronize the state of an application and an application's objects with data stored on the storage system. The storage system provides API's to create special data, called a marker journal, and stores it on a journal volume. The marker contains application information, e.g. file name, operation on the file, timestamp, etc. Since the journal volume contains markers as well as any changed data in the chronological order, IO activities to the storage system and application activities can be synchronized.
