Subject: [PATCH] futex.h: 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
|
