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
