But still possible. For example, using the toml file from Comment 4 with Seed 9675272854109691020 will crash in 95 steps. Or, without copy_file_range at all, it's possible to crash in 126 steps usi= ng seed 8637402481540764494 and this toml file: flen =3D 524288 nomsyncafterwrite =3D true [opsize] max =3D 131072 min =3D 65536 [weights] truncate =3D 1 fsync =3D 1 fdatasync =3D 1 punch_hole =3D 0 write =3D 10 read =3D 10 --=20 You are receiving this mail because: You are the assignee for the bug.=
