[PATCH] VFS: Fix memory leak with file leases 
  
  The patch 
  http://linux.bkbits.net:8080/linux-2.6/diffs/fs/locks.c@1.70??nav=index.html 
  introduced a pretty nasty memory leak in the lease code. When freeing 
  the lease, the code in locks_delete_lock() will correctly clean up 
  the fasync queue, but when we return to fcntl_setlease(), the freed 
  fasync entry will be reinstated. 
  
  This patch ensures that we skip the call to fasync_helper() when we're 
  freeing up the lease.
