Subject: ipmi: use SIGIO instead of SIGUSR2 to avoid conflict with JVM
X-Git-Tag: collectd-5.3.2~5^2
X-Git-Url: https://git.verplant.org/?a=commitdiff_plain;h=89b7a6dfb77e5529e5089bf6593ed9fd83202429;p=collectd.git

ipmi: use SIGIO instead of SIGUSR2 to avoid conflict with JVM

Java uses SIGUSR2 to suspend/resume threads. The OpenIPMI plugins also
need a signal to resume its event loop when setting a timer. They can't
both use the same signal. We ask OpenIPMI to use SIGIO instead.

This should fix #114.
