+Subject: [PATCH] Avoid acl_ prefix for functions
+
+The acl.h header from libacl uses acl_ prefix for its functions. Avoid
+defining functions with the same name in order to protect its namespace.
+
+Upstream: https://cgit.git.savannah.gnu.org/cgit/tar.git/commit/?id=08c3fc2e9337094aff01a511170fd35fdb8f1ee3
