6582408 ::arc should accept -k/-m/-g to print in kilo/mega/giga-bytes
6582438 should have generic reader-priority rwlock for spa_config locks
6582441 zfs_cmd_t should only be used to pass arguments to/from userland
6582456 property code is overdue for some spring cleaning
6588564 zpl unmount lock should use regular rwlock
