I can not try the patch, but maybe you can try LVM with the file?

dd count=102400 bs=1024 if=/dev/zero of=temp

parted --script temp \
mklabel msdos \
mkpart primary 8M 100% \
toggle 1 boot \
print

losetup /dev/loop0 temp

fdisk -ul /dev/loop0

pvcreate /dev/loop0
vgcreate lvm0-vol /dev/loop0

pvdisplay
vgscan
vgs

lvcreate --name storage --size 32M lvm0-vol

then use the storage device with tgtadm....

lvextend --size +32M /dev/lvm0-vol/storage

grow the logical volume..

see what happens with the tgtadm

Thanks in advance,

Kind regards,
