| Subject: libnvdimm, pfn: fix align attribute |
| |
| From: Dan Williams <dan.j.williams@intel.com> |
| |
| commit af7d9f0c57941b465043681cb5c3410f7f3f1a41 upstream. |
| |
| Fix the format specifier so that the attribute can be parsed correctly. |
| Currently it returns decimal 1000 for a 4096-byte alignment. |
