From 5070570c9089b905dd9efae30ee4318033c6ccd6 Mon Sep 17 00:00:00 2001 From: Namhyung Kim Date: Wed, 8 Nov 2017 00:31:34 +0900 Subject: [PATCH] trace: Simplify find_debugfs() The return vale of find_debugfs() is 1 if it could find a mount point of debugfs. It can be saved in the while loop instead of checking it again.
