This is the failing "swapon" sequence from updated Xenial i386 on
vmware:

Sequence is identical to other, native/amd64 system with same kernel
version but without the problem where swapon() will return 0.

Title:
swapon failed: invalid argument
Status in linux package in Ubuntu:
Confirmed
Status in util-linux package in Ubuntu:
Invalid
Bug description:
Environment:
- Ubuntu 18.04.1 LTS
- Linux 4.15.0-32-generic i686
Description:
When I try to mount my swap partition or my swap file, I get "swapon failed:
invalid argument" .
Steps to reproduce:
1) sudo bash
2) dd if=/dev/zero of=/swapfile bs=1024 count=524288
3) mkswap /swapfile
4) chown root:root /swapfile
5) chmod 0600 /swapfile
6) swapon /swapfile
Last execution returns "swapon failed: invalid argument" .
I'm almost sure it's a bug because I have no problems using Linux
4.15.0-29-generic instead of Linux 4.15.0-32-generic. Also, no
problems using Ubuntu 18.04.1 LTS Live CD.
Regards.
