Provide the acpi handle path as the location string for the nvdimm
children of the nvdimm_root device.
It looks like Phabricator will report that there are property changes on the directory but does not show the details - you can confirm that svn diff shows this metadata change:
Index: . =================================================================== --- . (revision 349048) +++ . (working copy) Property changes on: . ___________________________________________________________________ Modified: svn:mergeinfo ## -0,0 +0,1 ## Merged /head:r348757
@imp, thanks for pointing that out. I was following acpi's method https://svnweb.freebsd.org/base/head/sys/dev/acpica/acpi.c?revision=347984&view=markup#l853
I'll send a change for both of these and then squash that into this MFC.
