The swap mount point is not displayed correctly. The module is not locking for dm (device-mapper) on swap partition.
I use mdadm and lvm2, and my swap space is displayed 2 times. Once with /dev/dm-11 and once with LVM VG mapper, LV system-swap
Also once saved=yes and once saved=no

    is /dev/dm-11 a symlink on your system, and if so where does it link to?

    Ok sorry but after some research in the linux kernel is found out that the fstab device name is changed into kernel device mapper name, so /dev/system-swap is /dev/dm-11.
    The entry in /etc/fstab is different from /proc/swaps.
    Hm right now I'm looking to change this on the linux kernel, but won't be so easy it needs a lot of research...
    If you want take a look in the kernel tree under "mm/swapfile.c", and watch what is between "#ifdef CONFIG_PROC_FS" and "#endif /* CONFIG_PROC_FS */".

    This is no webmin bug, but rather a kernel bug.
    Sorry (I will rename the fstab entry into dm-11 to see if webmin is displaying it correctly and then post my answer)

    ok I renamed in the fstab file /dev/system-swap into /dev/dm-11 but the probleme is the same.
    well it is not a drastic problem, but the kernel should fix this :)
