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 from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
