This is a note to let you know that I have just added a patch titled dax_io(): don't let non-error value escape via retval instead of EFAULT to the linux-4.2.y-queue branch of the 4.2.y-ckt extended stable tree which can be found at: http://kernel.ubuntu.com/git/ubuntu/linux.git/log/?h=linux-4.2.y-queue This patch is scheduled to be released in version 4.2.8-ckt1.
