    llc: delete timers synchronously in llc_sk_free() · b905ef9a
    Cong Wang authored
    The connection timers of an llc sock could be still flying
    after we delete them in llc_sk_free(), and even possibly
    after we free the sock. We could just wait synchronously
    here in case of troubles.
    Note, I leave other call paths as they are, since they may
    not have to wait, at least we can change them to synchronously
    when needed.
    Also, move the code to net/llc/llc_conn.c, which is apparently
    a better place.
