nfsd4: preallocate nfs4_file in process_open1()
Creating a new file is an irrevocable step--once it's visible in the filesystem, other processes may have seen it and done something with it, and unlinking it wouldn't simply undo the effects of the create. Therefore, in the case where OPEN creates a new file, we shouldn't do the create until we know that the rest of the OPEN processing will succeed. For example, we should preallocate a struct file in case we need it until waiting to allocate it till process_open2(), which is already too late. Signed-off-by: J. Bruce Fields <bfields@redhat.com>
