Hi,

FYI, your patch has been queued to LTS release 17.11.5

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 01/04/19. So please
shout if anyone has objections.

Also note that after the patch there's a diff of the upstream commit vs the patch applied
to the branch. If the code is different (ie: not only metadata diffs), due for example to
a change in context or macro names, please double check it.

Thanks.

Yongseok

Subject: [PATCH] mbuf: explicit cast of size on detach

[ upstream commit c779ebdca0e4765158bd1eaa6f65c9d714605fae ]

GCC 8.1 warned:

In function 'rte_pktmbuf_detach':
rte_mbuf.h:1580:14: warning: conversion from 'long unsigned int'
to 'uint32_t' {aka 'unsigned int'} may change value [-Wconversion]
  mbuf_size = sizeof(struct rte_mbuf) + priv_size;
              ^~~~~~
