From b562c171cf011d297059bd0265742eb5fab0ad2f Mon Sep 17 00:00:00 2001 From: Kees Cook Date: Mon, 4 Dec 2017 17:24:54 -0800 Subject: locking/refcounts: Do not force refcount_t usage as GPL-only export The refcount_t protection on x86 was not intended to use the stricter GPL export. This adjusts the linkage again to avoid a regression in the availability of the refcount API.
