| H A D | sa.c | diff 226483 Mon Oct 17 20:25:44 MDT 2011 delphij Fix a bug in sa_find_sizes() which could lead to panic: When calculating space needed for SA_BONUS buffers, hdrsize is always rounded up to next 8-aligned boundary. However, in two places the round up was done against sum of 'total' plus hdrsize. On the other hand, hdrsize increments by 4 each time, which means in certain conditions, we would end up returning with will_spill == 0 and (total + hdrsize) larger than full_space, leading to a failed assertion because it's invalid for dmu_set_bonus.
