Subject: [PATCH] sd-journal: make sure it's safe to call sd_journal_process() |
|
before the first sd_journal_wait() |

In that case we have no inotify fd yet, and there's nothing to process |
|
hence. Let's make the call a NOP. |
|
|
|
(Previously, without this change we'd end up trying to read off inotify |
|
fd -1, which is quite a problem... 😢) |
|
|
|
