Subject: [PATCH 43/47] xfs: disable per-inode DAX flag
Date: Sun, 17 Sep 2017 14:07:08 -0700 [thread overview]
Message-ID: <20170917210712.10804-44-hch@lst.de> (raw)
In-Reply-To: <20170917210712.10804-1-hch@lst.de>
commit 742d84290739ae908f1b61b7d17ea382c8c0073a upstream.
Currently flag switching can be used to easily crash the kernel. Disable
the per-inode DAX flag until that is sorted out.
