Abstract
User process to directly access a file in a file system. A user process first opens a file in the file system for access. In the process of opening the file, a file handle for the file is returned to the user process by an operating system kernel. The user process then makes a read request to a special function unit for one or more blocks of the file in the file system using the file handle. In response, the special function unit, which is coupled to the processor, bypasses the operating system kernel and returns the requested data directly to the user process. A write by the user process may be refused by the computer system or allowed on a selective basis based on a flag in a file system inode corresponding to the block.
