Sure. In include/linux/sunrpc/xdr.h, I've now added:
/**
* xdr_encode_bool - Encode a boolean item
* @p: address in a buffer into which to encode
* @n: boolean value to encode
*
* Return value:
* Address of item following the encoded boolean
*/
static inline __be32 *xdr_encode_bool(__be32 *p, u32 n)
{
*p = n ? xdr_one : xdr_zero;
return p++;
}
and xdr_stream_encode_bool() has been changed to use this helper.
In fs/nfsd/nfs3xdr.c, the PATHCONF result encoder now uses
xdr_encode_bool() to encode the four boolean fields in struct
PATHCONF3resok.
