Hi, should anybody still use the blktap(1) driver in linux-2.6.18-xen, the following patch intends to make the maximum number of tapdevs configurable at module insertion time. The number is clamped to [256 .. NR_EVENT_CHANNELS]. I removed the definition of MAX_DEV_NAME because it didn't seem to be used at all. Thanks for considering, Laszlo Ersek
