Numbering of system calls

Numbering of system calls

[Rudolf Ladyzhenskii]

Hi, all

Kernel crashes and, among other things, it shows "Last syscall: 4".
How can I relate that to actual syscall being executed?

Thanks,

[ashish anand]

look in /usr/src/linux/arch/ppc/kernel/misc.S for syscall numbering...
syscall no. 4 is write -> sys_write

Sorry for my last "very interesting" message...

This is related to the last syscall executed by the current thread.
Have a look at $KERNELDIR/arch/ppc/kernel/process.c

For the corresponding system call you should look at the
$KERNELDIR/include/asm-ppc/unistd.h (or $KERNELDIR/arch/ppc/kernel/misc.S),
the 4th syscall is "write".

Fred
