From: Filipe Manana <fdmanana@xxxxxxxx> Currently btrfs/173 fails when passing "-o nodatacow" to MOUNT_OPTIONS because it assumes that when creating a file it does not have the nodatacow flag set, which is obviously not true if the fs is mounted with "-o nodatacow". To allow the test to run successfully with nodatacow, just make sure it clears the nodatacow flag from the file if the fs was mounted with "-o nodatacow".
