Subject: block/iscsi: drop unallocated_blocks_are_zero
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=32d293c8c668d4e0d19594d8af359627dd7260f9;p=qemu.git

block/iscsi: drop unallocated_blocks_are_zero

We set bdi->unallocated_blocks_are_zero = iscsilun->lbprz, but
iscsi_co_block_status doesn't return 0 in case of iscsilun->lbprz, it
returns ZERO when appropriate. So actually unallocated_blocks_are_zero
is useless (it doesn't affect the only user of the field:
bdrv_co_block_status()). Drop it now.
