Theodore Ts'o ed1e643a4f ext4: avoid race conditions when remounting with options that change dax ... [ Upstream commit 829b37b8cddb1db75c1b7905505b90e593b15db1 ] Trying to change dax mount options when remounting could allow mount options to be enabled for a small amount of time, and then the mount option change would be reverted. In the case of "mount -o remount,dax", this can cause a race where files would temporarily treated as DAX --- and then not.
