From 50229128727f7e11840ca1b2b501f880818d56b6 Mon Sep 17 00:00:00 2001 From: Dexuan Cui Date: Tue, 5 Jun 2018 13:37:52 -0700 Subject: [PATCH] Drivers: hv: vmbus: Fix the offer_in_progress in vmbus_process_offer() I didn't really hit a real bug, but just happened to spot the bug: we have decreased the counter at the beginning of vmbus_process_offer(), so we mustn't decrease it again.
