https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D137145 --- Comment #12 from Andriy Gapon <avg@FreeBSD.org> --- (In reply to Konstantin Belousov from comment #11) Perhaps Tx that is keeping its reference. I don't know what kind of code people can write to manipulate mbuf, this is just a theoretical example. Larger point is why have the special case, does it provide a lot of win for performance? I know that atomic operations are expensive. A branch is not free, however, too. Always doing the atomic update is straightforward and safe(r). --=20 You are receiving this mail because: You are the assignee for the bug.=
