3.5.7.3 -stable review patch. If anyone has any objections, please let me know.
------------------
From: Myron Stowe <myron.stowe at redhat.com>
commit 1278998f8ff6d66044ed00b581bbf14aacaba215 upstream.
Commit 284f5f9 was intended to disable the "only_one_child()" optimization
on Stratus ftServer systems, but its DMI check is wrong. It looks for
DMI_SYS_VENDOR that contains "ftServer", when it should look for
DMI_SYS_VENDOR containing "Stratus" and DMI_PRODUCT_NAME containing
"ftServer".
Tested on Stratus ftServer 6400.
