ext2: auto disable dax instead of failing mount Bring the ext2 filesystem in line with xfs that only warns and continues when the "-o dax" option is specified to mount and the backing device does not support dax. This is in preparation for removing dax support from devices that do not enable get_user_pages() operations on dax mappings. In other words 'gup' support is required and configurations that were using so called 'page-less' dax will be converted back to using the page cache. Removing the broken 'page-less' dax support is a pre-requisite for removing the "EXPERIMENTAL" warning when mounting a filesystem in dax mode.
