From 88e85a7daf8e21f2d6cb054374d480c540725cde Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Tue, 26 Jun 2018 12:55:35 +0900 Subject: bpfilter: check compiler capability in Kconfig With the brand-new syntax extension of Kconfig, we can directly check the compiler capability in the configuration phase. If the cc-can-link.sh fails, the BPFILTER_UMH is automatically hidden by the dependency. I also deleted 'default n', which is no-op.
