Hi all, I mentioned at LSF/MM that I wanted to revive this, and at the time there were no disagreements. I finally got around to refreshing the patch(es) so here goes. These patches introduce VM_PINNED infrastructure, vma tracking of persistent 'pinned' page ranges. Pinned is anything that has a fixed phys address (as required for say IO DMA engines) and thus cannot use the weaker VM_LOCKED. One popular way to pin pages is through get_user_pages() but that not nessecarily the only way. Roland, as said, I need some IB assistance, see patches 4 and 5, where I got lost in the qib and ipath code. Patches 1-3 compile tested. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx. For more info on Linux MM, see: http://www.linux-mm.org/ .
