Single transaction technique for a journaling file system of a computer operating system

A computer program product comprising:

• a propagating signal having computer readable code embodied therein for causing data to be written from a computer system to a mass storage device;
• computer readable code segment in the propagating signal comprising code configured to implement a logging device in the mass storage device;
• computer readable code segment in the propagating signal comprising code configured to implement a master device in the mass storage device;
• computer readable code segment in the propagating signal comprising code configured to process a plurality of file system operations using the computer system, wherein the file system operations are generated by an external application program and refer to data stored at a specified location in the master device;
• computer readable code segment in the propagating signal comprising code configured to provide an in-core copy of data from the master device for each file system operation;
• computer readable code segment in the propagating signal comprising code configured to alter the in-core copy of data from the master device for each file system operation;
• computer readable code segment in the propagating signal comprising code configured to write the altered in-core copy corresponding to each file system operation to the master device;
• computer readable code segment in the propagating signal comprising code configured to accumulate a plurality of the file system operations into a single logging transaction;
• and
• computer readable code segment in the propagating signal comprising code configured to perform the single logging transaction by writing the single logging transaction to the logging device.

A computer system having a processor and a memory operatively coupled to the processor, the computer system comprising:

• a mass storage device coupled to the processor for receiving data, the mass storage device having a logging device and a master device;
• an operating system executing on the processor, the operating system operatively coupled to application programs for performing a plurality of file system operations;
• a journaling file system implemented within the operating system, the journaling file system coupled to write log transactions to the logging device and file system transactions to the master device;
• and
• a transaction device within the journaling file system for creating a single log transaction for accumulating log records corresponding to a plurality of file system operations.
