Alan Somers 2d1c164591 Speed up geom_stats_resync in the presence of many devices ... The old code had a O(n) loop, where n is the size of /dev/devstat. Multiply that by another O(n) loop in devstat_mmap for a total of O(n^2). This change adds DIOCGMEDIASIZE support to /dev/devstat so userland can quickly determine the right amount of memory to map, eliminating the O(n) loop in userland. This change decreases the time to run "gstat -bI0.001" with 16,384 md devices from 29.7s to 4.2s. Also, fix a memory leak first reported as PR 203097.
