Currently when we back trace something that is in a syscall we see something like this: [c000000000000000] [c000000000000000] SyS_read+0x6c/0x110 [c000000000000000] [c000000000000000] syscall_exit+0x0/0x98 Although it's entirely correct, seeing syscall_exit at the bottom can be confusing - we were exiting from a syscall and then called SyS_read() ? If we instead change syscall_exit to be a local label we get something more intuitive: [c0000001fa46fde0] [c00000000026719c] SyS_read+0x6c/0x110 [c0000001fa46fe30] [c000000000009264] system_call+0x38/0xd0 ie. we were handling a system call, and it was SyS_read().
