Storing Data

Abstract

The invention provides a method of storing data in a computing device, the method including the steps of creating a memory file system in non-pageable kernel memory of the computing device, writing data to the memory file system and transferring the written data to a pageable memory space allocated to a user process running on the computing device. An advantage of such a design is that, initially, the data of the memory based file system can be kept in the non-pageable kernel memory, minimising the need to perform context switches. However, the data can be transferred to pageable memory when necessary, such that the amount of kernel memory used by the file system can be minimised.
