+Subject: [PATCH] [build] Remove -lboost_iostreams linker flag
+
+This was previously needed for thin-provisioning/thin_metadata_pack.cc
+but that file was rewritten in Rust and no longer needs Boost. The flag
+causes every binary to have a completely redundant depedency on
+libboost_iostream.so, which is an issue for RHEL packaging.
