v2:
 - Fixed author name: Aaron --> Aaron Mestdagh
 - Fixed patch index: [PATCH 4/4] package/fluent-bit: bump fluent-bit to 5.1.2 --> [PATCH v2]
   The old patch was on top of the "[v1,1/3] package/librdkafka: add new package" series.
   https://patchwork.buildroot.org/project/buildroot/list/?series=88&state=%2A&archive=both
 - Refreshed the merged 0001-lib-ripser-initialize-temporary-diameter-entry patch
 - Used msgpack-c 7.0.2 & librdkafka 2.16.0 to test, all `./utils/test-pkg -p fluent-bit -a` passed.

+Subject: [PATCH] lib: ripser: initialize temporary diameter entry
+
+GCC 6 does not accept implicit default construction of diameter_entry_t.
+The temporary is assigned before use, so initialize it with Ripser's existing
+invalid-index sentinel.
