From 74e6072894d6ccd9c950d1c9bce3870596731810 Mon Sep 17 00:00:00 2001 From: Masami Hiramatsu Date: Wed, 3 Jun 2020 11:40:49 +0900 Subject: [PATCH] selftests/ftrace: Convert check_filter_file() with requires list Since check_filter_file() is basically checking the filter tracefs file, we can convert it into requires list.
