AFAIK readdir is used to read an entire directory & lookup
is used to get the inode corresponding to a particular
directory entry. So its not neccessary that lookup will be called after readdir. For eg. doing an ls in /usr/src will call lookup("/usr/src"), which will return the inode corresponding to /usr/src directory, then readdir will be called to read the directory. (Please correct me if i am wrong).
>(this is my rough understanding). My question is I need >to check to see if a file has already been "filldir"ed.
Why do you need to do this ?
