hi,
i am developing a "fan-out stackable file system". for that i referred to fs like wrapfs (using fistgen 0.1.2). i want to know what exact calls are invoked when "ls" command is executed at the terminal. using "printk" debugging method i figured out that
open
readdir
...filldir
from file_operations
i used ramfs code, i then defined open and readdir functions and added printk, i compliled it as a module,inserted to kernel and mounted it.
and when i invoked "ls" at mount point, its not invoking open, readdir
can anyone please help me .
i'll be thankful to recieve any book or link reference related to this topic
