However, it doesn't add these to # __clear_user(), which is used in the ptrace regset code. # # As there's only one direct user of __clear_user(), and the time taken to # set the AMR for KUAP purposes is going to dominate the cost of a quick # access_ok(), there's not much point having a separate path. # # Rename __clear_user() to clear_user_asm(), and make __clear_user() just # call clear_user().
