Subject: [PATCH] journald: fix accuracy of watchdog timer event
|
|
|
dd65c9 |
|
|
|
dd65c9 |
Adding 3/4th of the watchdog frequency as accuracy on top of 1/2 of the
|
|
|
dd65c9 |
watchdog frequency means we might end up at 5/4th of the frequency which
|
|
|
dd65c9 |
means we might miss the message from time to time.

Maybe fixes #1804
