Subject: [dpdk-dev] [RFC 03/23] eal: No panic on hugepages info init
Date: Fri, 30 Dec 2016 10:26:00 -0500 [thread overview]
Message-ID: <1483111580-5397-4-git-send-email-aconole@redhat.com> (raw)
In-Reply-To: <1483111580-5397-1-git-send-email-aconole@redhat.com>
When attempting to scan hugepages, signal to the eal.c that an error has
occured, rather than performing a panic.
