Abstract

A method and apparatus for performing a reverse name lookup in a file system is described. A file system driver executing on the computing system agent may receive a reverse name lookup request for an inode number. The file system driver retrieves a disk inode, corresponding to the inode number, a first block number of a first directory entry (dentry), the first dentry identifying directory data blocks where the inode number and a file name are stored. The file system driver searches the first dentry for the inode number to find the corresponding file name, and retrieves the file name from the first dentry.
