Device and method on file system journaling using atomic operation

摘要

The present invention relates to an apparatus and method for file system journaling using atomic operations. More particularly, the present invention relates to a method and apparatus for receiving a plurality of pieces of information including additional information for an atomic operation together with a write request from an application program, determining whether there is an atomic write request among the received write requests, Writes the received plurality of pieces of information in a write buffer of a storage device when the result of the request is an atomic write request and if the plurality of pieces of information are recorded in the write buffer, And controls the mapping table of a translation translation layer (FTL) to be committed. Thus, it is possible to solve the consistency problem of the file system by using the storage device efficiently.
