The patch now compiles OK, but my first simple test shows that something
is obviously wrong with the patch.
Here are a set of user-space addresses that have been swapped out to disk:
crash> set 1
PID: 1
COMMAND: "systemd"
TASK: ffff92a13a1e8000 [THREAD_INFO: ffff92a13a260000]
CPU: 2
STATE: TASK_INTERRUPTIBLE
crash> vm -p | grep SWAP
55d917fb5000 SWAP: /dev/dm-2 OFFSET: 55827
55d917fb7000 SWAP: /dev/dm-2 OFFSET: 55828
55d917fc2000 SWAP: /dev/dm-2 OFFSET: 121359
55d917fc6000 SWAP: /dev/dm-2 OFFSET: 88579
55d917fcb000 SWAP: /dev/dm-2 OFFSET: 88581
55d917fcc000 SWAP: /dev/dm-2 OFFSET: 88582
55d917fcd000 SWAP: /dev/dm-2 OFFSET: 88583
55d917fce000 SWAP: /dev/dm-2 OFFSET: 104963
55d917fcf000 SWAP: /dev/dm-2 OFFSET: 104964
...
Obviously any read of the addresses above should fail, but each
read returns successfully, and each read is screwing up the internal
buffering scheme:
