| Subject: ia64: mmap: consider pgoff when searching for free mapping |
| Date: Fri, 21 Jul 2023 17:24:32 +0200 |
| |
| IA64 is the only architecture which does not consider the pgoff value when |
| searching for a possible free memory region with vm_unmapped_area(). |
| Adding this seems to have no negative side effect on IA64, so add it now |
| to make IA64 consistent with all other architectures. |
