Subject: [PATCH 1/3] skbuff: use kvfree() to deallocate head
Date: Thu, 22 Aug 2019 10:48:20 +0000	[thread overview]
Message-ID: <1566470851-4694-2-git-send-email-jan.dakinevich@virtuozzo.com> (raw)
In-Reply-To: <1566470851-4694-1-git-send-email-jan.dakinevich@virtuozzo.com>

If skb buffer was allocated using vmalloc() it will make simple its
further deallocation.
