Subject: MINOR: tasks: Allow tasklet_wakeup() to wakeup a task.
X-Git-Tag: v1.9-dev2~162
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=5d18718c8f85d43d3bc1c172e8538564ce0ad7ce;p=thirdparty%2Fhaproxy.git

MINOR: tasks: Allow tasklet_wakeup() to wakeup a task.

Modify tasklet_wakeup() so that it handles a task as well, and inserts it
directly into the tasklet list, making it effectively a tasklet.
This should make future developments easier.
