Hi, 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. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
