[sheepdog] [PATCH 00/11] sheepdog: reconnect server after connection failure

[MORITA Kazutaka]

Currently, if a sheepdog server exits, all the connecting VMs need to
be restarted.  This series implements a feature to reconnect the
server, and enables us to do online sheepdog upgrade and avoid
restarting VMs when sheepdog servers crash unexpectedly.

MORITA Kazutaka (11):
  ignore SIGPIPE in qemu-img and qemu-io
  iov: handle eof in iov_send_recv
  qemu-sockets: make wait_for_connect be invoked in qemu_aio_wait
  sheepdog: make connect nonblocking
  sheepdog: check return values of qemu_co_recv/send correctly
  sheepdog: handle vdi objects in resend_aio_req
  sheepdog: reload inode outside of resend_aioreq
  coroutine: add co_aio_sleep_ns() to allow sleep in block drivers
  sheepdog: try to reconnect to sheepdog after network error
  sheepdog: make add_aio_request and send_aioreq void functions
  sheepdog: cancel aio requests if possible
