The kernel includes three schedulers: anticipatory, deadline and (the default) CFQ, whereas the author refers only to "old" and "new" schedulers. I wonder which of the features he describes are common to all three. I also wonder which kernel version introduced the "new" scheduler. I have a reason for this interest, which I intend to describe in a separate thread. -- Rgds Peter Humphrey Linux Counter 5290, Aug 93 -- [EMAIL PROTECTED] mailing list
