I am having some trouble with an out of tree module for a virtual block
device driver. I need to disable the direct reclaim path when the device
is used as swap. I cannot see a way to detect that the device is being
used as swap, so I am currently disabling it unconditionally.
Is there a clean way to detect that the block device is being used as
swap? I am not subscribed to the list, so please CC replies to me.
