Hello, I know absolutely nothing about arch/mips, I can't even find the definition of "current" or the caller of switch_to(). So, __sanitize_fcr31() is called by switch_to() and it does force_fcr31_sig(fcr31, pc, next). Was "current" already updated at this stage so that next == current? Why I am asking. I want to add // otherwise the usage of ->siglock is not safe WARN_ON(!(t == current || task_is_traced(t))); into force_sig_info_to_task() and simplify it a bit, but I don't know if "t == current" is already true at the start of switch_to(). Thanks, Oleg.
