Subject: MINOR: tasks: Add __task_get_new_tid_field()
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=8b6d8f5e4f921f5ebb60a0e18de2bd12da136dc5;p=thirdparty%2Fhaproxy.git

MINOR: tasks: Add __task_get_new_tid_field()

Introduce __task_get_new_tid_field(), that provides the tid to be used
for a task.
For shared task, to mark temporary ownership of a task, instead of -1,
the tid will be set to -2-tid, tid being the tid of the current thread.
