+Subject: [PATCH] fanotify.h: fix build with uclibc
+
+MAX_HANDLE_SZ is used since version 20200515 and
+https://github.com/linux-test-project/ltp/commit/d20a3e8f9a794e0659277acfa9fbcf7454ba4631
+
+However, it is not defined by uclibc, so define it if needed to avoid
+the following build failure:
+
+fanotify.h:171:11: error: 'MAX_HANDLE_SZ' undeclared here (not in a function)
+  171 |  char buf[MAX_HANDLE_SZ];
