If an NFS server returns a filehandle that we have previously seen, and reports a different type, then nfs_refresh_inode() will log a warning and return an error. nfs_fhget() does not check for this error and may return an inode with a different type than the one that the server reported. This is likely to cause confusion, and is one way that ->open_context() could return a directory inode as discussed in the previous patch. So if nfs_refresh_inode() returns and error, return that error from nfs_fhget() to avoid the confusion propagating.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
