Subject: mempool: uninline function to check cookies
X-Git-Tag: spdx-start~6898
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=8dcb12707e4127335c2bd26ddf597d284feba99a;p=dpdk.git

mempool: uninline function to check cookies

There's no reason to keep this function inlined. Move it to
rte_mempool.c. We need to export the function for when compiling
with shared libraries + debug. We also need to keep the macro,
because we don't want to call an empty function when debug is
disabled.
