13  * syscall_get_nr - find what system call a task is executing
17  * If @task is executing a system call or is at system call
18  * tracing about to attempt one, returns the system call number.
19  * If @task is not executing a system call, i.e. it's blocked
23  * system call number can be meaningful.  If the actual arch value
34  * syscall_rollback - roll back registers after an aborted system call
35  * @task:	task of interest, must be in system call exit tracing
38  * It's only valid to call this when @task is stopped for system
41  * the system call from taking place.
44  * system call instruction was a no-op.  The registers containing
45  * the system call number and arguments are as they were before the
46  * system call instruction.  This may not be the same as what the
47  * register state looked like at system call entry tracing.
55  * syscall_get_error - check result of traced system call
59  * Returns 0 if the system call succeeded, or -ERRORCODE if it failed.
62  * from a system call, due to %TIF_SYSCALL_TRACE or %TIF_SYSCALL_AUDIT.
71  * syscall_get_return_value - get the return value of a traced system call
75  * Returns the return value of the successful system call.
79  * from a system call, due to %TIF_SYSCALL_TRACE or %TIF_SYSCALL_AUDIT.
87  * syscall_set_return_value - change the return value of a traced system call
93  * This changes the results of the system call that user mode will see.
94  * If @error is zero, the user sees a successful system call with a
96  * code; the user sees a failed system call with this errno code.
99  * from a system call, due to %TIF_SYSCALL_TRACE or %TIF_SYSCALL_AUDIT.
108  * syscall_get_arguments - extract system call parameter values
115  * Fetches @n arguments to the system call starting with the @i'th argument
120  * entry to a system call, due to %TIF_SYSCALL_TRACE or %TIF_SYSCALL_AUDIT.
121  * It's invalid to call this with @i + @n > 6; we only support system calls
150  * syscall_set_arguments - change system call parameter value
151  * @task:	task of interest, must be in system call entry tracing
157  * Changes @n arguments to the system call starting with the @i'th argument.
162  * entry to a system call, due to %TIF_SYSCALL_TRACE or %TIF_SYSCALL_AUDIT.
163  * It's invalid to call this with @i + @n > 6; we only support system calls
