Author: delphij Date: Mon Oct 13 20:39:51 2014 New Revision: 273060 URL: https://svnweb.freebsd.org/changeset/base/273060 Log: Use write_psize instead of write_asize when doing vdev_space_update. Without this change the accounting of L2ARC usage would be wrong and give 16EB free space because the number became negative and overflows.
