Subject: [PATCH] src/util/futex.h: fix build on 32-bit architectures using
|
64-bit time_t
|
|
Fix the following build failure on 32-bit architectures using 64-bit
|
time_t (e.g. riscv32):
|
|
../src/util/futex.h: In function 'sys_futex':
|
../src/util/futex.h:39:19: error: 'SYS_futex' undeclared (first use in this function); did you mean 'sys_futex'?
|
39 | return syscall(SYS_futex, addr1, op, val1, timeout, addr2, val3);
|
| ^~~~~~~~~
|
| sys_futex
|
