[dpdk-dev] [PATCH v3 01/12] common/dpaax: move internal symbols into INTERNAL section

[Hemant Agrawal (OSS)]

Hi Ray,
	I could not find validate_abi using libabigail.abignore.  Am I missing something. 
Though check_abi.sh uses it. 

When I am checking with validate_abi.sh, I still see warnings.

Regards,
Hemant
