It means individual FS can call in a generic atomic write validation
helper instead of implementing of their own. Hence generic_atomic_write_valid(). 

So for e.g. blkdev_atomic_write_valid() function and maybe iomap (or
ext4 or xfs) can use a generic_atomic_write_valid() helper routine to
validate an atomic write request.
