From 9449925273933d19235d7d36c1fd970841d055de Mon Sep 17 00:00:00 2001 From: Alexandros Batsakis Date: Wed, 20 Oct 2010 00:17:56 -0400 Subject: NFS: change stateid to be a union In NFSv4.1 the stateid consists of the other and seqid fields. For layout processing we need to numerically compare the seqid value of layout stateids. To do so, introduce a union to nfs4_stateid to switch between opaque(16 bytes) and opaque(12 bytes) / __be32 Signed-off-by: Alexandros Batsakis Signed-off-by: Benny Halevy Signed-off-by: Fred Isaman Signed-off-by: Trond Myklebust --- fs/nfs/callback_proc.c | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) (limited to 'fs/nfs/callback_proc.c') diff --git a/fs/nfs/callback_proc.c b/fs/nfs/callback_proc.c index 930d10fecda..2950fca0c61 100644 --- a/fs/nfs/callback_proc.c +++ b/fs/nfs/callback_proc.c @@ -118,11 +118,11 @@ int nfs41_validate_delegation_stateid(struct nfs_delegation *delegation, const n if (delegation == NULL) return 0; - /* seqid is 4-bytes long */ - if (((u32 *) &stateid->data)[0] != 0) + if (stateid->stateid.seqid != 0) return 0; - if (memcmp(&delegation->stateid.data[4], &stateid->data[4], - sizeof(stateid->data)-4)) + if (memcmp(&delegation->stateid.stateid.other, + &stateid->stateid.other, + NFS4_STATEID_OTHER_SIZE)) return 0; return 1; -- cgit v1.2.3
