[Qemu-devel] [PATCH 0/3] nbd: fix issues when connection breaks |

The first patch ensures the nbd_receive_reply() fd handler is unregistered when
the connection to the server breaks. This avoids high CPU consumption and
flooding error messages.
The second patch introduces an NBD server fault injection script. Using this
fake NBD server it is possible to exercise error handling code paths in the NBD
client.
The third patch adds qemu-iotests test case 080 to verify qemu-io exits with an
error at each point where the connection can break.
Stefan Hajnoczi (3):
nbd: close socket if connection breaks
tests: add nbd-fault-injector.py utility
qemu-iotests: add 080 NBD client disconnect tests
