3.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Peng Tao <bergw...@gmail.com>
commit dc182549d439f60c332bf74d7f220a1bccf37da6 upstream.
After commit e38eb650 (NFS: set_pnfs_layoutdriver() from
nfs4_proc_fsinfo()), set_pnfs_layoutdriver() is called inside
nfs4_proc_fsinfo(), but pnfs_blksize is not set. It causes setting
blocklayoutdriver failure and pnfsblock mount failure.
