BUG/MAJOR: threads/tasks: fix the scheduler again
My recent change in commit ce4e0aa ("MEDIUM: task: change the construction
of the loop in process_runnable_tasks()") was bogus as it used to keep the
rq_next across an unlock/lock sequence, occasionally leading to crashes for
tasks that are eligible to any thread. We must use the lookup call for each
new batch instead. The problem is easily triggered with such a configuration :
global
nbthread 4
listen check
mode http
bind 0.0.0.0:8080
redirect location /
option httpchk GET /
server s1 127.0.0.1:8080 check inter 1
server s2 127.0.0.1:8080 check inter 1
Thanks to Olivier for diagnosing this one. No backport is needed.
