In util-linux 2.26 and onward a check is done to see if there are any
open filehandles on the device that is being updated. Specifically,
this check is being done in 'is_device_used': disk-utils/sfdisk.c:1055
For loopback devices the ioctl(fd, BLKRRPART) will always fail with
return code -1. Checking errno will yield error '22'. This is
"expected" and parted has considered making exceptions for this in the
past [1]. I would propose that instead of having to iss ue a '--force'
flag for basic loopback device operation, an exception should be
included in the is_device_used function.
It could be as simple as:
+ // If we are dealing with a loopback device this will fail, but
shouldn't
+ if (!strncmp("/dev/loop", fdisk_get_devname(sf->cxt), 9)) {
+ return 0;
+ }
