Subject: [Bug 201259] [xfstests shared/010]: maybe pagecache contents is mutated after cycle mount

--- Comment #5 from Eric Sandeen (sandeen@sandeen.net) ---
Even simpler,
xfs_io -f -c "pwrite -S 0x72 0 4096" $DONOR1
xfs_io -f \
-c "falloc -k 8192 4096" \
-c "pwrite -S 0x57 65536 8192" \
-c "fdatasync" \
-c "reflink $DONOR1 0 131072 4096" \
$TARGET
so this seems to be an extending reflink extending past/into speculative
preallocation which exposes the stale blocks.
