Wu Fengguang 1ebf26a9b3 readahead: make mmap_miss an unsigned int ... This makes the performance impact of possible mmap_miss wrap around to be temporary and tolerable: i.e. MMAP_LOTSAMISS=100 extra readarounds. Otherwise if ever mmap_miss wraps around to negative, it takes INT_MAX cache misses to bring it back to normal state. During the time mmap readaround will be _enabled_ for whatever wild random workload. That's almost permanent performance impact.
