Subject: [PATCH v2 11/29] vmlinux.lds.h: Replace RODATA with RO_DATA
Date: Thu, 10 Oct 2019 17:05:51 -0700
Message-ID: <20191011000609.29728-12-keescook@chromium.org> (raw)
In-Reply-To: <20191011000609.29728-1-keescook@chromium.org>

There's no reason to keep the RODATA macro: replace the callers with
the expected RO_DATA macro.
