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)"
