+Subject: [PATCH] innobase: Define __NR_futex if it does not exist
+
+__NR_futex is not defines by newer architectures e.g. arc, riscv32 as
+they only have 64bit variant of time_t. Glibc defines SYS_futex interface based
+on
+__NR_futex, since this is used in applications, such applications start
+to fail to build for these newer architectures. This patch defines a
+fallback to alias __NR_futex to __NR_futex_tim64 so SYS_futex keeps
+working
+
+Upstream-Status: Pending
