+Subject: [PATCH] nilfs_cleanerd: link dynamically
+
+When nilfs_cleanerd does not run due to shared object problems,
+nilfs2 filesystems may run out of space soon.
+This logic that justified linking nilfs_cleanerd statically
+does IMO not apply to embedded systems built by buildroot.
+This commit therefore drops the static linking.

+
+rpc/types.h does not exist on low-footprint musl toolchains,
+and is only required for the boolean types, which musl provides

+This commit drops the include completely.
