Subject: [PATCH 2/5] fs/xfs: Isolate the physical DAX flag from effective
Date: Sun, 20 Oct 2019 08:59:32 -0700	[thread overview]
Message-ID: <20191020155935.12297-3-ira.weiny@intel.com> (raw)
In-Reply-To: <20191020155935.12297-1-ira.weiny@intel.com>

From: Ira Weiny <ira.weiny@intel.com>

xfs_ioctl_setattr_dax_invalidate() currently checks if the DAX flag is
changing as a quick check.

But the implementation mixes the physical (XFS_DIFLAG2_DAX) and
effective (S_DAX) DAX flags.

Remove the use of the effective flag when determining if a change of the
physical flag is required.
