Remove that parameter in the whole gup // stack. // // This changed the function signature from: // // long get_user_pages(struct task_struct *tsk, struct mm_struct *mm, // unsigned long start, unsigned long nr_pages, // unsigned int gup_flags, struct page **pages, // struct vm_area_struct **vmas); // // to // // long get_user_pages(struct mm_struct *mm, // unsigned long start, unsigned long nr_pages, // unsigned int gup_flags, struct page **pages, // struct vm_area_struct **vmas); // long gupr_wrapper(struct mm_struct *mm, unsigned long start, unsigned long nr_pages, unsigned int gup_flags, struct page **pages, struct vm_area_struct **vmas) { return get_user_pages(mm, start, nr_pages, gup_flags, pages, vmas); } Save
