Date: Fri, 30 Aug 2019 10:41:10 +0900 From: Austin Kim <austindh.kim@...il.com> To: darrick.wong@...cle.com Cc: linux-xfs@...r.kernel.org, linux-kernel@...r.kernel.org, austindh.kim@...il.com Subject: [PATCH] xfs: Use WARN_ON_ONCE for bailout mount-operation If the CONFIG_BUG is enabled, BUG is executed and then system is crashed. However, the bailout for mount is no longer proceeding. Using WARN_ON_ONCE rather than BUG can prevent this situation.
