3. Patch for "ext4: fix fault handling when mounted with -o dax,ro"

There was a regression (see this 4.11.1 commit) on the readonly DAX enabled readonly ext4 support.

If you are building kernel >= 4.11.1, you would need to pick up the following fix for this regression to be able to use PMEM devices for Docker layers.
