Hello,
Does anybody know how to get the logical block numbers of file accesses?
i.e. if I want to read some data from a file, how can I know which block
numbers I am accessing? Is there any system call?
Thank you!
regards,
Yijian Wang

ioctl (fd, FIBMAP, &block)
You have to run this as root, though
