Subject: zap_other_threads: remove unneeded ->exit_signal change
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=a4798833d26b293fd18b7bf102991426aa0b56fd;p=openwrt%2Fstaging%2Fblogic.git

zap_other_threads: remove unneeded ->exit_signal change

We already depend on fact that all sub-threads have ->exit_signal == -1, no
need to set it in zap_other_threads().
