Re: [PATCH] [14/48] Suspend2 2.1.9.8 for 2.6.12: 404-check-mounts-support.patch

[Nigel Cunningham <ncunningham@cyclades.com>]

Sorry.

It's not really a bug in the swapoff code. Rather, clearing this field
allows simple identification of the devices being used for swap (for
flushing writes).

Regards,

Nigel

Evolution.
Enumerate the requirements.
Consider the interdependencies.
Calculate the probabilities.
