vma_shrink() is only used by relocate_vma_down() to shrink the tail of a VMA. Therefore neither the start nor the pgoff parameters make any sense. It seemed we were passing the pgoff parameter solely to satisfy vma_set_range()'s requirement for pgoff being specified. Since vma_set_range() is now isolated to vma.c, we can simply introduce __vma_set_range() which sets only vma->vm_[start, end], and invoke this instead, removing start and pgoff from vma_shrink() altogether. No functional change intended. Reviewed-by: Pedro Falcato <pfalcato@suse.de> Signed-off-by: Lorenzo Stoakes <ljs@kernel.org>
