Subject: ovs-ctl: Add additional options to strace wrapper.
X-Git-Tag: sliver-openvswitch-1.8.90-0~48^2~307
X-Git-Url: http://git.onelab.eu/?a=commitdiff_plain;h=da2db2cb3114341d837c6f13ae8104d4b4bf4659;p=sliver-openvswitch.git

ovs-ctl: Add additional options to strace wrapper.

It's useful to know how long each system call took, and at what
time each system call happened.  In addition this patch causes
strace to print strings more fully allowing log messages to be seen
in the output.
