    [PATCH] seqlock for xtime · bb59cfa4
    Stephen Hemminger authored
    Add "seqlock" infrastructure for doing low-overhead optimistic reader
    locks (writer increments a sequence number, reader verifies that no
    writers came in during the critical region, and lots of careful memory
    barriers to take care of business).
    
    Make xtime/get_jiffies_64() use this new locking.
