[PATCH v2 5/9] mm: Initialize struct vm_unmapped_area_info

2024-02-26 Thread Rick Edgecombe
Future changes will need to add a field to struct vm_unmapped_area_info. This would cause trouble for any archs that don't initialize the struct. Currently every user sets each field, so if new fields are added, the core code parsing the struct will see garbage in the new field. It could be possib
