You can use it from userspace like this: http://smackerelofopinion.blogspot.com/2009//fibmap-ioctl-file-system-block-number.html If that is what you want to do, you can do the same thing from the kernel, you can look up ioctl_fibmap in fs/ioctl.c and see if you get what you need. -Abhijit _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
