Anything playing with get_user_pages(tsk, ...) with tsk != current is very much a part of VM guts. While we are at it, do_generic_file_read() *is* in mm/filemap.c. And signals and pipes are also "a kind of IPC", so the rationale is really weak. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
