ext4: fix no journal corruption with locale-gen
If there is no journal, ext4_should_writeback_data() should return TRUE. This will fix ext4_set_aops() to set ext4_da_ops in the case of delayed allocation; otherwise ext4_journaled_aops gets used by default, which doesn't handle delayed allocation properly. The advantage of using ext4_should_writeback_data() approach is that it should handle nobh better as well. Thanks to Curt Wohlgemuth for investigating this problem, and Aneesh Kumar for suggesting this approach. Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
