+Subject: [PATCH 1/2] Use system-compatible include path for `xxhash.h`
+
+Distributors that build mold against the system-provided xxHash package
+expect its header file `xxhash.h` in the top-level include directory,
+not in an `xxhash` subdirectory. Adjust the include path and the
+`#include` directive accordingly.

+%description
+mold is a faster drop-in replacement for existing Unix linkers.
+It is several times faster than the LLVM lld linker.
+mold is designed to increase developer productivity by reducing
+build time, especially in rapid debug-edit-rebuild cycles.
