Subject: timeval: Do not block SIGALRM around setting 'deadline' in time_alarm().
X-Git-Tag: sliver-openvswitch-1.10.90-3~6^2~159
X-Git-Url: http://git.onelab.eu/?a=commitdiff_plain;h=a19b84f4a6f0716ff641750c2aa0785c0e6e59b5;p=sliver-openvswitch.git

timeval: Do not block SIGALRM around setting 'deadline' in time_alarm().

There is no need to do so because the signal handler does not read or
write 'deadline'.
