+            
+            This PR updates `src/libltfs/uthash.h` to the latest version from the uthash submodule.
+            
+            **Changes:**
+            - Updated uthash submodule to latest commit
+            - Copied uthash.h from submodule to src/libltfs/
+            
+            **Note:** The OOM handling macros are defined in `uthash_ext.h` and remain unchanged.
