NFSv4: Fix an Oops in the synchronous write path
- Missing initialisation of attribute bitmask in _nfs4_proc_write() - On success, _nfs4_proc_write() must return number of bytes written. - Missing post_op_update_inode() in _nfs4_proc_write() - Missing initialisation of attribute bitmask in _nfs4_proc_commit() - Missing post_op_update_inode() in _nfs4_proc_commit() Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
