Hi, in criu we intensively use additional information provided by /proc/<pid>/fdinfo/<fd> particular to the object opened file represents. The output is printed out by file_operations::show_fdinfo method and the implementation of this method is pretty simple. Still I think better would be to convert this method to seq_operations pointer where all suppliers (epoll, eventfd and such) provide own seq-file operations. While this makes code a little more complex this will decrease the amount of kernel memory needed for output (because we won't need to provide all information in one pass but by chunks).
Please take a look, thanks! -- 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/
