Dear maintainer,

this is what I meant to write:

When I try to sparsify a certain, already sparsified file using
"fallocate -vd", it reproducibly reports to have freed up 2 KiB, which
it hasn't. The file in question is:

Name: debian-10.10.0-amd64-DLBD-2.iso
Size: 23552321536
MD5: 3cfa82ba8faab8f3e11b108f23a274f3

Transcript:

$ du debian-10.10.0-amd64-DLBD-2.iso
23000320        debian-10.10.0-amd64-DLBD-2.iso

$ fallocate -vd debian-10.10.0-amd64-DLBD-2.iso
debian-10.10.0-amd64-DLBD-2.iso: 330 KiB (337920 bytes) converted to
sparse holes.

$ du debian-10.10.0-amd64-DLBD-2.iso
22999992        debian-10.10.0-amd64-DLBD-2.iso

$ fallocate -vd debian-10.10.0-amd64-DLBD-2.iso
debian-10.10.0-amd64-DLBD-2.iso: 2 KiB (2048 bytes) converted to sparse
holes.

$ du debian-10.10.0-amd64-DLBD-2.iso
22999992        debian-10.10.0-amd64-DLBD-2.iso

Best regards
