Linux: Revisiting Swap Prefetch

Filed under
Linux

Another thread discussed potentially merging the swap prefetch patch into the mainline Linux kernel. Con Kolivas started the thread saying "I fixed all bugs I could find and improved it as much as I could last kernel cycle. Put me and the users out of our misery and merge it now or delete it forever please."

Replying to an off-list message, Andrew Morton asked users of the patch, "please provide us more details on your usage and testing of that code. Amount of memory, workload, observed results, etc?"

Nick Piggin noted that he's still interested in better understanding and possibly fixing what's happening with swap and reclaim on the systems reporting a benefit from the swap-prefetch patch.
