Brian Behlendorf 954fe5e1be Add interface to interface spa_get_worst_case_min_alloc() function ... Provide an interface to retrieve the lowest and highest minimum allocation size for the normal allocation class. This can be used by external consumers of the DMU to estimate potential wasted capacity when setting the recordsize for an object. The new "min_alloc" and "max_alloc" keys are added to the pool configuration and used by default_volblocksize() to warn when an ineffecient block size is requested. For older kmods which don't yet include the new keys fallback to the previous logic.
