From ad6d41253bf91eabb41626683c35a712ba27a20c Mon Sep 17 00:00:00 2001 From: Vitaly Kuznetsov Date: Sat, 28 Jan 2017 12:37:16 -0700 Subject: [PATCH] Drivers: hv: balloon: add a fall through comment to hv_memory_notifier() Coverity scan gives a warning when there is fall through in a switch without a comment. This fall through is intentional as ol_waitevent needs to be completed to unblock hv_mem_hot_add() allowing it to process next requests regardless of the result of if we were able to online this block.
