Add a userspace filtering tool for page_owner that supports per-fd filtering with print_mode and NUMA node filters. Features: - Three print modes: stack (default), handle, stack_handle - NUMA node filtering with flexible formats (single: 0, multiple: 0,1,2, range: 0-3, mixed: 0,2-3) - Per-file-descriptor filter state for independent filtering Usage examples: # Filter by print mode ./page_owner_filter -m handle ./page_owner_filter -m stack_handle # Filter by NUMA node ./page_owner_filter -n 0 ./page_owner_filter -n 0-3 # Combined filters ./page_owner_filter -m stack -n 0,1,2 ./page_owner_filter -m handle -n 0,2-3 The tool validates inputs before sending commands to the kernel and provides clear error messages when the kernel does not support per-fd filtering.
