https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=265974 --- Comment #3 from Konstantin Belousov <kib@FreeBSD.org> --- I believe you are right, but I would wait for an opinion of people who spent a time with smr code. That said, atomic_add_acq on x86 has the sequentially consistent semantic already (which is why you said that it works on Intel, right?). So the #ifdef from the patch in smr_enter() is not needed, use seq_cst fence for all arches. -- You are receiving this mail because: You are the assignee for the bug.
