| 4 | Subject: [PATCH] innobase: Define __NR_futex if it does not exist |
| 5 | |
| 6 | __NR_futex is not defines by newer architectures e.g. arc, riscv32 as |
| 7 | they only have 64bit variant of time_t. Glibc defines SYS_futex interface based |
| 8 | on |
| 9 | __NR_futex, since this is used in applications, such applications start |
| 10 | to fail to build for these newer architectures. This patch defines a |
| 11 | fallback to alias __NR_futex to __NR_futex_tim64 so SYS_futex keeps |
| 12 | working |
| 13 | |
| 14 | Upstream-Status: Pending |
