From 78a6e620515a0ca7e3481a9d8277225c800262a7 Mon Sep 17 00:00:00 2001 From: Pavel Cahyna Date: Wed, 24 Jun 2026 18:45:30 +0200 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.
