Subject: BUG/MEDIUM: tasklets: Add the thread as active when waking a tasklet.
X-Git-Tag: v1.9-dev2~138
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=abedf5f6c37a4f21cf9c68e1e0f408218eb54a84;p=thirdparty%2Fhaproxy.git

BUG/MEDIUM: tasklets: Add the thread as active when waking a tasklet.

Set the flag for the current thread in active_threads_mask when waking a
tasklet, or we will never run it if no tasks are available.

This is 1.9-specific, no backport is needed.
