This would overwrite\n some or all of the kernel buffer\n - copy kernel (LLD) buffer back to the user space.\n\nThe idea was to detect short reads by filling the original\nuser space buffer with some marker bytes (\"0xec\" it would\nseem in this report). The \"resid\" value is a better way\nof detecting short reads but that was only added this century\nand requires co-operation from the LLD.\n\u003d\n\nThis patch changes the block layer mapping API to support this\nsemantics.
