fast user-space locking
sys_futex(u32 *uaddr, int op, u32 val, const struct __kernel_timespec *utime, u32 *uaddr2, u32 val3)| number | 422 (0x1a6) |

Registers
| register | value |
|---|---|
a2 | 422, the syscall number |
a6 | u32 *uaddr |
a3 | int op |
a4 | u32 val |
a5 | const struct __kernel_timespec *utime |
a8 | u32 *uaddr2 |
a9 | u32 val3 |
a2 | the return value |
Then run syscall to enter the kernel.
