ext4: let getattr report the right blocks in delalloc+bigalloc
In delayed allocation, i_reserved_data_blocks now indicates clusters, not blocks. So report it in the right number. This can be easily exposed by the following command: echo foo > blah; du -hc blah; sync; du -hc blah Reported-by: Eric Sandeen <sandeen@redhat.com> Signed-off-by: Tao Ma <boyu.mt@taobao.com> Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
