In the inline assembler I MYSELF put arguments in the places where MY (by the

r11 is saved by the caller so this is the generated code is valid.
Since nothing else uses r11 in the inline-asm, the code is correct.
The problem is not that r11 not saved at

Or you can subq $128, %rsp; call my_syscall; addq $128, %rsp in your inline

The problem is not that r11 not saved at stack, but that saved on the stack

From the i386.h header:
The value is zero if the register is not call used
