NR_syscalls macro holds the number of system call exist in m68k architecture. We have to change the value of NR_syscalls, if we add or delete a system call. One of the patch in this patch series has a script which will generate a uapi header based on syscall- .tbl file. The syscall.tbl file contains the total number of system calls information. So we have two option to update NR_syscalls value. 1. Update NR_syscalls in asm/unistd.h manually by counting the no.of system calls. No need to up- date NR_syscalls until we either add a new sys- tem call or delete existing system call. 2. We can keep this feature it above mentioned sc- ript, that will count the number of syscalls and keep it in a generated file. In this case we don't need to explicitly update NR_syscalls in asm/unistd.h file. The 2nd option will be the recommended one. For that, I added the __NR_syscalls macro in uapi/asm/unistd.h along with NR_syscalls asm/unistd.h. The macro __NR- _syscalls also added for making the name convention same across all architecture. While __NR_syscalls isn't strictly part of the uapi, having it as part of the generated header to simplifies the implement- ation. We also need to enclose this macro with #ifdef __KERNEL__ to avoid side effects. Signed-off-by: Firoz Khan <firoz.khan@linaro.org> Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org> |
