    nfsd4: simplify lease/grace interaction · e46b498c
    J. Bruce Fields 提交于
    The original code here assumed we'd allow the user to change the lease
    any time, but only allow the change to take effect on restart.  Since
    then we modified the code to allow setting the lease on when the server
    is down.  Update the rest of the code to reflect that fact, clarify
    variable names, and add document.
    
    Also, the code insisted that the grace period always be the longer of
    the old and new lease periods, but that's overly conservative--as long
    as it lasts at least the old lease period, old clients should still know
    to recover in time.
