Subject: [PATCH] sd-event: always reshuffle time prioq on changing
812ca2
 online/offline state
812ca2
812ca2
Before 81107b8419c39f726fd2805517a5b9faab204e59, the compare functions
812ca2
for the latest or earliest prioq did not handle ratelimited flag.
812ca2
So, it was ok to not reshuffle the time prioq when changing the flag.
812ca2
812ca2
But now, those two compare functions also compare the source is
812ca2
ratelimited or not. So, it is necessary to reshuffle the time prioq
812ca2
after changing the ratelimited flag.
812ca2
812ca2
Hopefully fixes #19903.
