Subject: 0108-top: Always exit from sig_abexit().
X-Git-Tag: v4.0.0~573
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=e1f419737f01618181686281ae98347e03163e56;p=procps-ng

0108-top: Always exit from sig_abexit().

The default action for SIGURG is to ignore the signal, for example.
This is very similar to the patch "ps/display.c: Always exit from
signal_handler()."
