Ryan Stone 660344ca44 Add a VM flag to prevent reclaim on a failed contig allocation ... If a M_WAITOK contig alloc fails, the VM subsystem will try to reclaim contiguous memory twice before actually failing the request. On a system with 64GB of RAM I've observed this take 400-500ms before it finally gives up, and I believe that this will only be worse on systems with even more memory. In certain contexts this delay is extremely harmful, so add a flag that will skip reclaim for allocation requests to allow those paths to opt-out of doing an expensive reclaim.
