## Environment

kernel-default-5.7.rc1-1.1.g84ddad4.x86_64
systemd-244-3.1.x86_64
util-linux-2.35.1-1.1.x86_64


## Expected behavior

image.0.raw is a whole dist image file
# losetup --find --show --partscan ~/image.0.raw

would created devices for the image plus the partitions
/dev/loop0
/dev/loop0p1
/dev/loop0p2


## Actual behavior

# losetup --find --show --partscan ~/image.0.raw

creates only the top device /dev/loop0

> Apr 20 16:54:30 blackbook kernel: loop_reread_partitions: partition scan of loop2 (/home/mkoutny/image.0.raw) failed (rc=-16)


## Observation
- this started happening after upgrade of kernel-default (from
  5.6.0-rc7-1.g0801cd7-default) or util-linux (from 2.34-4.4)
- SIGSTOPping udevd during losetup call allows the scan to succeed
