Tested with a pynfs test that removes the pynfs server delegation stateid and return NFS4ERR_BAD_STATEID upon a READ. Andy Adamson (1): NFSv4.1 do not clear NFS_DELEAGED_STATE until stateid is tested Trond Myklebust (2): NFSv4.1: Fix the checking of the stateid when returning a delegation NFS: Properly handle the case where the delegation is revoked fs/nfs/callback_proc.c | 6 +++--- fs/nfs/delegation.c | 13 ++++++++++++- fs/nfs/delegation.h | 1 + fs/nfs/nfs4_fs.h | 2 ++ fs/nfs/nfs4proc.c | 16 ++++++++++++++-- fs/nfs/nfs4state.c | 31 ++++++++++++++++++++++++++++++- 6 files changed, 62 insertions(+), 7 deletions(-) -- 1.7.6.4
