    mac80211: introduce plink lock for plink fields · 48bf6bed
    Bob Copeland authored Apr 13, 2015
    
    
    The mesh plink code uses sta->lock to serialize access to the
    plink state fields between the peer link state machine and the
    peer link timer.  Some paths (e.g. those involving
    mps_qos_null_tx()) unfortunately hold this spinlock across
    frame tx, which is soon to be disallowed.  Add a new spinlock
    just for plink access.
