#     
#     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)"
