Subject: [RFC Patch v3 08/18] blktap2: use correct way to define array.
Date: Fri, 5 Sep 2014 17:10:51 +0800	[thread overview]
Message-ID: <1409908261-18682-9-git-send-email-wency@cn.fujitsu.com> (raw)
In-Reply-To: <1409908261-18682-1-git-send-email-wency@cn.fujitsu.com>

Currently, we use the following way to define an array:
type array[] = {
    [index] = xxx,
    0,
};
So array[index+1] will be NULL. If index is not the last
index, it will override another index.

tapdisk_vbd_index is not defined, but array[DISK_TYPE_VINDEX]
is overridden, so we don't find this problem when building
the source.
