From 0dd3c19212961453817f219cd6200981c38564bc Mon Sep 17 00:00:00 2001 From: NeilBrown Date: Thu, 23 Jun 2005 22:02:56 -0700 Subject: [PATCH] [PATCH] nfsd4: support CLAIM_DELEGATE_CUR Add OPEN claim type NFS4_OPEN_CLAIM_DELEGATE_CUR to nfsd4_open(). A delegation stateid and a name are provided. OPEN with O_CREAT is not legal with this claim type; otherwise, use the NFS4_OPEN_CLAIM_NULL code path to lookup the filename to be opened.
