Subject: test/mem: refactor and rename functions
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=6324cc5cf71cdb07b42bdf57531060958dc0cd75;p=dpdk.git

test/mem: refactor and rename functions

We will be adding a new extmem test that will behave roughly similar
to already existing, so clarify function names to distinguish between
these tests, as well as factor out the common parts.
