The change to rdma-core.spec in commit b631ce466538bdee6e19be3286fb8cbeb5c73de6:
...
+# 32-bit arm is missing required arch-specific memory barriers,
+ExcludeArch: %{arm}
...
should have been communicated to all depdent package maintainers in
advance, as this is effectively removing the package for armv7hl from
rawhide. Cc'ing the committer.
Why was this built on arm32 before if RDMA is not support arm32?
