From 73a99f083009d67d8e12603420e008d5c21b0b7d Mon Sep 17 00:00:00 2001 From: "Michael S. Tsirkin" Date: Tue, 23 Feb 2010 11:23:45 +0200 Subject: [PATCH] vhost: initialize log eventfd context pointer vq log eventfd context pointer needs to be initialized, otherwise operation may fail or oops if log is enabled but log eventfd not set by userspace. When log_ctx for device is created, it is copied to the vq. This reset was missing. Reviewed-by: Juan Quintela Signed-off-by: Michael S.
