New Revision: 285154
URL: https://svnweb.freebsd.org/changeset/base/285154
Log:
Remove extra level of target ID indirection (isp_dev_map).
FreeBSD never had limitation on number of target IDs, and there is no
any other requirement to allocate them densely. Since slots of port
database already populated just sequentially, there is no much need
for another indirection to allocate sequentially too.
