+Subject: [PATCH] tests: fix portability issue when using __NR_mmap syscall
+
+On some architectures e.g. ARM and RISCV32, __NR_mmap does not exist and
+libc will then use NR_mmap2 to implement mmap() API, therefore use
+system C library mmap() API instead of calling the syscall directly
+
+Upstream-Status: Partial Backport [https://github.com/axboe/liburing/commit/808b6c72ab753bda0c300b5683cfd31750d1d49b]
