+Subject: [PATCH] Fix protocol minor version fall-back
+
+mount.nfs currently expects mount(2) to fail with EPROTONOSUPPORT if
+the kernel doesn't understand the requested NFS version.
+
+Unfortunately if the requested minor is not known to the kernel
+it returns -EINVAL.
+In kernels since 3.11 this can happen in nfs4_alloc_client(), if
+compiled without NFS_V4_2.
+
+More generally it can happen in in nfs_validate_text_mount_data()
+when nfs_parse_mount_options() returns 0 because
+nfs_parse_version_string()
+didn't recognise the version.
+
+EPROTONOSUPPORT is only returned if NFSv4 support is completely compiled
+out.
+
+So nfs_autonegotiate needs to check for EINVAL as well as
+EPROTONOSUPPORT.
