[dpdk-dev] [PATCH v7 05/14] eal: do not panic on memzone initialization fails

[Aaron Conole]

When memzone initialization fails, report the error to the calling
application rather than panic().  Without a good way of detaching /
releasing hugepages, at this point the application will have to restart.
