#     
#     Pull libnvdimm fixes from Dan Williams:
#      "A fix for a crash scenario that has been present since the initial
#       merge, a minor regression in sysfs attribute visibility, and a fix for
#       some flexible array warnings.
#     
#       The bulk of this pull is an update to the libnvdimm unit test
#       infrastructure to test non-ACPI platforms. Given there is zero
#       regression risk for test updates, and the tests enable validation of
#       bits headed towards the next merge window, I saw no reason to hold the
#       new tests back. Santosh originally submitted this before the v5.11
#       window opened.
#     
#       Summary:
#     
#        - Fix a crash when sysfs accesses race 'dimm' driver probe/remove.
#     
#        - Fix a regression in 'resource' attribute visibility necessary for
#          mapping badblocks and other physical address interrogations.
#     
#        - Fix some flexible array warnings
#     
#        - Expand the unit test infrastructure for non-ACPI platforms"
