+Subject: [PATCH] Fix failures in isc netmgr_test on big endian machines
+
+Typing from libuv structure to isc_region_t is not possible, because
+their sizes differ on 64 bit architectures. Little endian machines seems
+to be lucky and still result in test passed. But big endian machine such
+as s390x fails the test reliably.
+
+Fix by directly creating the buffer as isc_region_t and skipping the
+type conversion. More readable and still more correct.
+
+(cherry picked from commit 057438cb45f2f02615dc309e3822f23c0ca70a0a)
