There is a duplicated (and unneeded) call to memset above. Also, the
LV FIXME was a comment introduced by Laurent Vivier in commit bd81d8ee
because at the time input->block_bitmap was a 32-bit value. In the
new ext4_new_group_data structure, input->block_bitmap is now a 64-bit
field, so the need for "LV FIXME" is gone, and should be removed.
I'll remove the duplicate memset() calls and the "LV FIXME".
For future reference, this is why it's better to use something
descriptive about the FIXME "64-bit FIXME", as opposed to your
initials. And it's best if there's an explicit comment explaining why
the fixme is there (and what the consequences of leaving partially
broken code in the kernel :-), so that future code maintainers won't
have to do code archeology to figure out what the FIXME is all about.
