| From | "Kirill A. Shutemov" <> | Subject | [PATCH 05/34] mm: allow pgtable_page_ctor() to fail | Date | Thu, 10 Oct 2013 21:05:30 +0300 |
| |
Change pgtable_page_ctor() return type from void to bool. Returns true, if initialization is successful and false otherwise.
Current implementation never fails, but it will change later.
