Paul Clements 7fdfd4065c NBD: allow hung network I/O to be cancelled ... Allow NBD I/O to be cancelled when a network outage occurs. Previously, I/O would just hang, and if enough I/O was hung in nbd, the system (at least user-level) would completely hang until a TCP timeout (default, 15 minutes) occurred. The patch introduces a new ioctl NBD_SET_TIMEOUT that allows a transmit timeout value (in seconds) to be specified. Any network send that exceeds the timeout will be cancelled and the nbd connection will be shut down. I've tested with various timeout values and 6 seconds seems to be a good choice for the timeout. If the NBD_SET_TIMEOUT ioctl is not called, you get the old (I/O hang) behavior.
