    syscall_get_arch: add "struct task_struct *" argument · 16add411
    Dmitry V. Levin authored
    This argument is required to extend the generic ptrace API with
    PTRACE_GET_SYSCALL_INFO request: syscall_get_arch() is going
    to be called from ptrace_request() along with syscall_get_nr(),
    syscall_get_arguments(), syscall_get_error(), and
    syscall_get_return_value() functions with a tracee as their argument.
    
    The primary intent is that the triple (audit_arch, syscall_nr, arg1..arg6)
    should describe what system call is being called and what its arguments
    are.
