This is a note to let you know that I've just added the patch titled NFS: Correct size calculation for create reply length to the 5.11-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: nfs-correct-size-calculation-for-create-reply-length.patch and it can be found in the queue-5.11 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 4116276a718a1d76172bf73b097224c59b96b9a4 Author: Frank Sorenson <sorenson@xxxxxxxxxx> Date: Mon Mar 8 12:12:13 2021 -0600 NFS: Correct size calculation for create reply length [ Upstream commit ad3dbe35c833c2d4d0bbf3f04c785d32f931e7c9 ] CREATE requests return a post_op_fh3, rather than nfs_fh3. The post_op_fh3 includes an extra word to indicate 'handle_follows'. Without that additional word, create fails when full 64-byte filehandles are in use. Add NFS3_post_op_fh_sz, and correct the size calculation for NFS3_createres_sz.
