Tue Jul 29 15:38:15 1997 Thomas Bushnell, n/BSG <thomas@gnu.ai.mit.edu>

	* name-cache.c (check_lookup_cache): Use name_cache_neg_timeout in
	preference to name_cache_timeout for negative hits.

	* nfs.h (name_cache_neg_timeout): New variable.
	* main.c (DEFAULT_NAME_CACHE_NEG_TIMEOUT): New macro.
	(name_cache_neg_timeout): Initialize new variable.
	(OPT_NCACHE_NEG_TO): New option key.
	(common_options): Add --name-cache-neg-timeout switch.
	(parse_common_opt): Process OPT_NCACHE_NEG_TO option key.

	* ops.c (netfs_attempt_lookup): Do cast of -1 correctly to match
	check_lookup_cache and ANSI C rules.

	* name-cache.c (check_lookup_cache): Unlock DIR correctly before
	returning a negative cache hit.

	* rpc.c (rpc_receive_thread): Don't print "dropping reply"
	messages any more.

	* ops.c (netfs_attempt_lookup): Cash all lookups, both positive
	and negative.
	(netfs_attempt_mkdir): Purge cache before creating directory
	entry.
	(netfs_attempt_link): Likewise.
	(netfs_attempt_create_file): Likewise.

	* ops.c (netfs_attempt_lookup): Pass correct node to
	enter_lookup_cache as the child.

	* name-cache.c: New file.
	* ops.c (netfs_attempt_lookup): Check lookup cache before trying
	RPC.  After successful lookup, make cache entry.
	(netfs_attempt_unlink): Purge cache before doing operation.
	(netfs_attempt_rmdir): Likewise.
	(netfs_attempt_rename): Purge cache for both names before operation.
	* nfs.h (enter_lookup_cache, purge_lookup_cache,
	check_lookup_cache): New prototypes.
	* Makefile (SRCS): Add name-cache.c.

	* nfs.h (name_cache_timeout): New variable.
	* main.c (DEFAULT_NAME_CACHE_TIMEOUT): New macro.
	(name_cache_timeout): Initialize new variable.
	(OPT_NCACHE_TO): New option key.
	(common_options): Add --name-cache-timeout switch.
	(parse_common_opt): Process OPT_NCACHE_TO option key.

	* cache.c (lookup_fhandle): Don't parse NFS XDR format, instead
	take a length arg.  Return void.  All callers changed to use new
	function xdr_decode_fhandle.
	* nfs.c (xdr_decode_fhandle): New function.
	* nfs.h (xdr_decode_fhandle): New prototype.
	(lookup_fhandle): Update prototype.
