commit: dc182549d439f60c332bf74d7f220a1bccf37da6 From: Peng Tao <[email protected]> Date: Fri, 24 Aug 2012 00:27:49 +0800 Subject: NFS41: fix error of setting blocklayoutdriver
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.
