https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D229106 --- Comment #10 from John Baldwin <jhb@FreeBSD.org> --- To be clear, we are not talking about adding a spin mutex. We are talking about replacing the existing sched_lock mutex used to schedule the ithread anyway with a dedicated spin mutex that protects the list of handlers and c= an be used as the THREAD_LOCK when scheduling the ithread since ithreads are changed in this patch to set td_lock to the new mutex when they are idle. = You can't get away from the mutex to call sched_add(), but this lets you change what lock is now used for that in essence. --=20 You are receiving this mail because: You are the assignee for the bug.=
