| 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 |
