New Revision: 310646
URL: https://svnweb.freebsd.org/changeset/base/310646
Log:
Do not update "saved" mode page on every MODE SELECT.
We do not have non-volatile memory to really save those values, so we
neither report nor support this capability. Also saved mode pages are
not replicated between HA peers now.
