Merge tag 'libnvdimm-fixes-4.20-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm
Pull libnvdimm fixes from Dan Williams: "A small batch of fixes for v4.20-rc3. The overflow continuation fix addresses something that has been broken for several releases. Arguably it could wait even longer, but it's a one line fix and this finishes the last of the known address range scrub bug reports. The revert addresses a lockdep regression. The unit tests are not critical to fix, but no reason to hold this fix back. Summary: - Address Range Scrub overflow continuation handling has been broken since it was initially merged. It was only recently that error injection and platform-BIOS support enabled this corner case to be exercised. - The recent attempt to provide more isolation for the kernel Address Range Scrub state machine from userapace initiated sessions triggers a lockdep report. Revert and try again at the next merge window. - Fix a kasan reported buffer overflow in libnvdimm unit test infrastrucutre (nfit_test)" * tag 'libnvdimm-fixes-4.20-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm: Revert "acpi, nfit: Further restrict userspace ARS start requests" acpi, nfit: Fix ARS overflow continuation tools/testing/nvdimm: Fix the array size for dimm devices.
