    File System Doubt


    HOW do I create a partition called disk.img and mount it with esf4 module (ext4 file system module). Then I am supposes to run ftrace utility found in debugfs so as to trace the system calls in the kernel.

    Can anyone help me how to proceed with this.I have created the partitions with a set of command and also mounted,but I am not sure whether I have done correctly?I have also tried to run ftrace and able to trace some functions but I am not sure whether they are wrt esf4 module

    Whats is esf4 module will do? I have no clue about it. Whats your exact requirement? Do you want to analyse debugfs code or ext4 code?

    @Sam: First umount the file system and fsck command on the created partition.
    If there are any errors, it will display as the output.
