:After reading

:(last question) I noticed that we seem to have the same makro.
:Though I don't know any details, it looks wrong to me too.
:The problematic part is:
:
:#define ssb_lock(ssb, wf) ((ssb)->ssb_flags & SSB_LOCK ? \
:                (((wf) == M_WAITOK) ? _ssb_lock(ssb) : EWOULDBLOCK) : \
:                ((ssb)->ssb_flags |= SSB_LOCK), 0)
:
:
:that in its current form always evaluates to 0.

    Interesting.  That could account for some of the weird network bugs that
    have cropped up over the years.  Ours definitely has the same bug.

    I think I'll convert it to the inline version mentioned in the article.
