Well, it's a BUG_ON. It's supposed to be for something that "can't happen". That's why it's a sanity check, not a wild assertion. ;-) The 2/2 patch is an example of a bug that CHECK_FULL_REGS catches. In the status quo, using PTRACE_PEEKUSR in a bug case crashes while using PTRACE_GETREGS in the same place might get bogus data. (In the actual bug thus found, the data is not bogus and only the bit that FULL_REGS checks is.)
