Re: [PATCH] block: remove BLK_DEV_DAX config option

The functionality for block device DAX was already removed with this commit: commit acc93d30d7d4 ("Revert "block: enable dax for raw block devices"") However, we still had a config option hanging around that was always disabled because it depended on CONFIG_BROKEN. This config option was introduced in this commit: commit 03cdadb04077 ("block: disable block device DAX by default") This change reverts that commit, removing the dead config option.
