Refactor the encoder for FATTR4_CHANGE into a helper. In a subsequent patch, this helper will be called from a bitmask loop. The code is restructured a bit to use the modern xdr_stream flow, and the encoded cinfo value is made const so that callers of the encoders can be passed a const cinfo. Reviewed-by:

Refactor the encoder for FATTR4_TYPE into a helper. In a subsequent patch, this helper will be called from a bitmask loop. In addition, restructure the code so that byte-swapping is done on constant values rather than at run time. Run-time swapping can be costly on some platforms, and "type" is a frequently-requested attribute. Reviewed-by:

I'm about to split nfsd4_encode_fattr() into a number of smaller functions. Instead of passing a large number of arguments to each of the smaller functions, create a struct that can gather the common argument variables into something with a convenient handle on it. Reviewed-by:

For alignment with the specification, the name of NFSD's encoder function should match the name of the XDR type. I've also replaced a few "naked integers" with symbolic constants that better reflect the usage of these values. Reviewed-by:

The generic XDR encoders return a length or a negative errno. NFSv4 encoders want to know simply whether the encode ran out of stream buffer space. The return values for server-side encoding are either nfs_ok or nfserr_resource. So far I've found it adds a lot of duplicate code to try to use the generic XDR encoder utilities when encoding the simple data types in the NFSv4 operation encoders. Add a set of NFSv4-specific utilities that handle the basic XDR data types. These are added in xdr4.h so they might eventually be used by the callback server and pNFS driver encoders too.

There is no need to take down the whole system for these assertions. I'd rather not attempt a heroic save here, as some bug has occurred that has left the transport data structures in an unknown state. Just warn and then leak the left-over resources. Acked-by:

If the GETATTR request on a file that has write delegation in effect and the request attributes include the change info and size attribute then the request is handled as below: Server sends CB_GETATTR to client to get the latest change info and file size. If these values are the same as the server's cached values then the GETATTR proceeds as normal. If either the change info or file size is different from the server's cached values, or the file was already marked as modified, then: . update time_modify and time_metadata into file's metadata with current time . encode GETATTR as normal except the file size is encoded with the value returned from CB_GETATTR . mark the file as modified If the CB_GETATTR fails for any reasons, the delegation is recalled and NFS4ERR_DELAY is returned for the GETATTR.

sp_lock is now only used to protect sp_all_threads. This isn't needed as sp_all_threads is only manipulated through svc_set_num_threads(), which is already serialized. Read-acccess only requires rcu_read_lock(). So no more locking is needed. Signed-off-by:
