From a9f7b4a06c9704fa3cfe0b0601347e03289a7407 Mon Sep 17 00:00:00 2001 From: Kinglong Mee Date: Mon, 9 Dec 2013 19:31:21 +0800 Subject: [PATCH] nfsd: clean up an xdr reserved space calculation We should use XDR_LEN to calculate reserved space in case the oid is not a multiple of 4. RESERVE_SPACE actually rounds up for us, but it's probably better to be careful here. Signed-off-by: Kinglong Mee Signed-off-by: J.
