However,\nif one were to know that the incoming I/O stream was /very/ random in\nnature, the cycles are wasted.\n\nThis patch adds a per-request_queue tunable that (when set) disables\nmerge attempts (beyond the simple one-hit cache check), thus freeing up\na non-trivial amount of CPU cycles.\n\nSigned-off-by: Alan D.
