Hello,

It looks like a regression in 4.15.0-rc1 -- the test case simply run a
set of parallel dd's and there seems no reason to run into memory problem.

It occurs in 1 out of 4 tests.

The test goes like this:

        https://git.kernel.org/pub/scm/linux/kernel/git/wfg/vm-scalability.git/tree/case-lru-file-readtwice

        mount -t tmpfs -o size=100% vm-scalability-tmp /tmp/vm-scalability-tmp
        truncate -s 67192406016 /tmp/vm-scalability-tmp/vm-scalability.img
        mkfs.xfs -q /tmp/vm-scalability-tmp/vm-scalability.img
        mount -o loop /tmp/vm-scalability-tmp/vm-scalability.img /tmp/vm-scalability-tmp/vm-scalability
        ./case-lru-file-readtwice
        truncate /tmp/vm-scalability-tmp/vm-scalability/sparse-lru-file-readtwice-1 -s 39268272420
        truncate /tmp/vm-scalability-tmp/vm-scalability/sparse-lru-file-readtwice-2 -s 39268272420
        truncate /tmp/vm-scalability-tmp/vm-scalability/sparse-lru-file-readtwice-3 -s 39268272420
        ...
        truncate /tmp/vm-scalability-tmp/vm-scalability/sparse-lru-file-readtwice-112 -s 39268272420

The test machine is
