    I'm trying to modify the ordering of I/O requests in Linux kernel, and
    came across the barrier flags REQ_HARDBARRIER and REQ_SOFTBARRIER.

    One thing I noticed (which might be wrong) is that all the requests
    have both these flags set. What is the significance of these flags? Is
    it a must for a request to have this? Can I reorder two requests with
    these flags set? How is SOFTBARRIER different from HARDBARRIER?

    I appreciate your time and help.

    Thanks much.
