[PATCH 1/6] ipmi: decreases the IPMI message transaction time ininterrupt mode

From: Corey Minyard
Date: Fri Feb 03 2012 - 10:48:27 EST


From: Srinivas_Gowda <srinivas_g_gowda@xxxxxxxx>

Call the event handler immediately after starting the next message.

This change considerably decreases the IPMI transaction time (cuts off
~9ms for a single ipmitool transaction).
