Subject: [PATCH] journalctl: do not treat EINTR as an error when waiting for
events
Fixup for 2a1e0f2228bbdfbc18635e959f47df7da50b62fe. Fixes #10724.
Reproducer: start 'journalctl -f' in a terminal window, change window size.
(cherry picked from commit 8e143a123276a9636987b08f555603927ca9e186)
Resolves: #2161683
