s390utils/s390-tools-2.16.0-genprotimg.patch

From b6bdd7744aba06d82f30b0c84012f0b06ccb01de Mon Sep 17 00:00:00 2001

Subject: [PATCH] genprotimg: use `pv_` namespace for our Buffer implementation
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Use `pv_` namespace for our Buffer implementation so a symbol clash with other
libraries is less likely.

Fixes: https://github.com/ibm-s390-linux/s390-tools/issues/109
