      nfsd4: hash closed stateid's like any other · f7a4d872
      由 J. Bruce Fields 提交于 
      Look up closed stateid's in the stateid hash like any other stateid
rather than searching the close lru.

This is simpler, and fixes a bug: currently we handle only the case of a
close that is the last close for a given stateowner, but not the case of
a close for a stateowner that still has active opens on other files.
Thus in a case like:

	open(owner, file1)
	open(owner, file2)
	close(owner, file2)
	close(owner, file2)

the final close won't be recognized as a retransmission.

      nfsd4: construct stateid from clientid and counter · d3b313a4
      由 J. Bruce Fields 提交于 
      Including the full clientid in the on-the-wire stateid allows more
reliable detection of bad vs. expired stateid's, simplifies code, and
ensures we won't reuse the opaque part of the stateid (as we currently
do when the same openowner closes and reopens the same file).

      nfsd41: try to check reply size before operation · 58e7b33a
      由 Mi Jinlong 提交于 
      For checking the size of reply before calling a operation,
we need try to get maxsize of the operation's reply.

v3: using new method as Bruce said,

 "we could handle operations in two different ways:

	- For operations that actually change something (write, rename,
	  open, close, ...), do it the way we're doing it now: be
	  very careful to estimate the size of the response before even
	  processing the operation.
	- For operations that don't change anything (read, getattr, ...)
	  just go ahead and do the operation.  If you realize after the
	  fact that the response is too large, then return the error at
	  that point.

  So we'd add another flag to op_flags: say, OP_MODIFIES_SOMETHING.  And for
  operations with OP_MODIFIES_SOMETHING set, we'd do the first thing.  For
  operations without it set, we'd do the second."
