If anyone has any objections, please let me know. ------------------ From: Chuck Lever commit 202f39039a11402dcbcd5fece8d9fa6be83f49ae upstream. According to RFC 8881, all minor versions of NFSv4 support PUTPUBFH. Replace the XDR decoder for PUTPUBFH with a "noop" since we no longer want the minorversion check, and PUTPUBFH has no arguments to decode. (Ideally nfsd4_decode_noop should really be called nfsd4_decode_void). PUTPUBFH should now behave just like PUTROOTFH.
