When you move swap locations, an old swap file is left on the previous
device. This file can be erased by hand post-reboot, however it should be
cleaned up automatically.
Process:
* Swap file location changed by user
* Swap file is in use by os... so it can't be erased
* After reboot, kernel uses new swap file specified.
* Old swap file still exists.
This is generally a problem of knowing where the old swap file *was* on
reboot. a syscall may be a good solution (not requiring a reboot for
swapfile changes, maybe a _kern_swap_reprovision call that will:
* Make the kernel erase the flush the swap file into memory (if possible)
* Make the kernel erase the current swap file from disk, and re-read the
virtual_memory config to set up the new swap file.
