    md: rename mddev->write_lock to mddev->lock · 85572d7c
    NeilBrown authored
    This lock is used for (slightly) more than helping with writing
    superblocks, and it will soon be extended further.  So the
    name is inappropriate.
    
    Also, the _irq variant hasn't been needed since 2.6.37 as it is
    never taking from interrupt or bh context.
    
    So:
      -rename write_lock to lock
      -document what it protects
      -remove _irq ... except in md_flush_request() as there
         is no wait_event_lock() (with no _irq).  This can be
         cleaned up after appropriate changes to wait.h.
