The new code is the swap-on-NFS infrastructure, which indirects
swapfile accesses through the filesystem code. The reason you have to
do that with NFS is because NFS doesn't expose a block device at all,
so you can't get a list of blocks on an underlying device because
there isn't one. Indirecting the accesses through the filesystem,
however, allows us to side-step btrfs's problems with part (b) above,
and in theory gives us swapfile capability.
I was not even aware there was "new code" on the matter.
Is there a guide or whatever to doing this? I didn't see any mention of
it in the places Google led me.
