    Subject[PATCH 5.5 094/151] ktest: Add timeout for ssh sync testing
    Date
    From: Steven Rostedt (VMware) <rostedt@goodmis.org>

    commit 4d00fc477a2ce8b6d2b09fb34ef9fe9918e7d434 upstream.

    Before rebooting the box, a "ssh sync" is called to the test machine to see
    if it is alive or not. But if the test machine is in a partial state, that
    ssh may never actually finish, and the ktest test hangs.

    Add a 10 second timeout to the sync test, which will fail after 10 seconds
    and then cause the test to reboot the test machine.
