[lvm-devel] [PATCH LVM2] (5/12) allow preference to small area

[Jun'ichi Nomura]

This patch allows allocation request to prefer small area.

o _comp_area_inv() is used to reverse the areas[] sorting
  if the allocation request is ALLOC_PREFER_SMALL.

o In _find_parallel_space(), iteration for pv_area didn't work
  work as commented:
                /*
                 * Put the smallest area of each PV that is at least the
                 * size we need into areas array.  If there isn't one
                 * that fits completely and we're allowed more than one
                 * LV segment, then take the largest remaining instead.
                 */
  because of the "goto next_pv" at the end.
