+From 590e31dff8aa4c5ff8be761128e38ac751aed875 Mon Sep 17 00:00:00 2001

+Subject: [PATCH] event: fix wakeup consumption
+
+The events on a multi wakeup socketpair were only consumed via
+curl_multi_poll()/curl_multi_wait() but not in event based processing on
+a curl_multi_socket() call. That led to busy loops as reported in
+
+Fixes #21547
+Reported-by: Earnestly on github
+Closes #21549
+
+Upstream-Status: Backport ["2a2104f event: fix wakeup consumption"]
+Suggested-by: Ross Burton <ross.burton@arm.com>
