They are motivated by seeing issues with mbuf copying\nin rte_pdump and realized this a wider and more general problem.\nThe pdump copy could not handle different size pools and did\nnot handle meta data, etc.\n\nThey cause no functional or ABI changes. The only visible part\nto older code is converting a couple of inlines to real functions.\nThis kind of change confuses checkpatch which thinks these new\nfunctions should be marked experimental when they must not be.\n\nv4 - common mbuf header fields copy routine\nv3 - split linearize into internal/external\n copy private data in pktmbuf_copy\nv2 - add pdump use of pktmbuf_copy\n fix version in map\n\n\nStephen Hemminger (4):\n mbuf: don't generate invalid mbuf in clone test\n mbuf: delinline rte_pktmbuf_linearize\n mbuf: deinline rte_pktmbuf_clone\n mbuf: add a pktmbuf copy routine\n\n app/test/test_mbuf.c | 3 +\n lib/librte_mbuf/rte_mbuf.c | 145 +++++++++++++++++++++++++++\n lib/librte_mbuf/rte_mbuf.h | 127 +++++++++--------------\n lib/librte_mbuf/rte_mbuf_version.map | 8 ++\n 4 files changed, 206 insertions(+), 77 deletions(-)" }
