4 | Subject: [PATCH] futex.h: 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 on | ||
8 | __NR_futex, since this is used in applications, such applications start | ||
9 | to fail to build for these newer architectures. This patch defines a | ||
10 | fallback to alias __NR_futex to __NR_futex_tim64 so SYS_futex keeps | ||
11 | working | ||
12 | |||
