I have changed title of the bug. This is more precisely describe the problem. In my code, I do mmap.close(), so msync does not called. Generally, calling msync() on read-only mapping is not needed at all. And meven more, calling msync() on memory-mapped USB-camera will lead to EIO errno I think, that flush() should be no-op if mapping is read-only.
