[PATCH v1 2/3] perf record: apply affinity masks when reading mmap buffers

Build node cpu masks for mmap data buffers. Bind AIO data buffers to nodes according to kernel data buffers location. Apply node cpu masks to trace reading thread every time it references memory cross node or cross cpu. Signed-off-by: Alexey Budankov --- tools/perf/builtin-record.c | 9 ++
