3.14-stable review patch. If anyone has any objections, please let me know.
------------------ From: "J. Bruce Fields" <[email protected]> commit 082f31a2169bd639785e45bf252f3d5bce0303c6 upstream. This reverts the part of commit 6e14b46b91fee8a049b0940333ce13a820beaaa5 that changes NFSv2 behavior. Mark Lord found that it broke nfs-root for Linux clients, because it broke NFSv2. In fact, from RFC 1094: "Notice that the file type is specified both in the mode bits and in the file type. This is really a bug in the protocol and will be fixed in future versions." So NFSv2 clients really are expected to depend on the high bits of the mode. Reported-by: Mark Lord <[email protected]> Reviewed-by: Jeff Layton <[email protected]> Signed-off-by: J.
