[ewg] [PATCH 2/2] IB/iser: Ask the user to stop open-iscsi before stopping openibd on RH4

[Erez Zilber]

In RedHat 4, some OFED kernel modules (including open-iscsi modules)
use symbols that are encapsulated in ib_core (e.g. kfifo). ib_core
may not be unloaded before open-iscsi is unloaded. Therefore, disconnecting
from open-iscsi over iSER sessions is not suffiecient if the user tries to
stop openibd. The user must be prompted to stop open-iscsi before stopping
openibd.
