Subject: [PATCH] xfs: Use WARN_ON rather than BUG() for bailout mount-operation
Date: Wed, 28 Aug 2019 15:47:49 +0900 [thread overview]
Message-ID: <20190828064749.GA165571@LGEARND20B15> (raw)
If the CONFIG_BUG is enabled, BUG() is executed and then system is crashed.
However, the bailout for mount is no longer proceeding.
For this reason, using WARN_ON rather than BUG() could prevent this situation.
