From 9acd6442c6839d404c1f47dc0f3ff3e0fb13e44c Mon Sep 17 00:00:00 2001 From: "K. Y. Srinivasan" Date: Sat, 1 Dec 2012 06:46:51 -0800 Subject: Drivers: hv: Get rid of the unused global signaling state Now that we have implemented a per-connection signaling mechanism, get rid of the global signaling state. For hosts that don't support per-connection signaling handle, we have moved the global state to be a per-channel state. Signed-off-by: K. Y.
