Pass ds_commit_idx through the nfs commit path. It's used to select the commit bucket when using pnfs and is ignored when not using pnfs. Several functions had to be changed: nfs_retry_commit, nfs_mark_request_commit, pnfs_mark_request_commit and the pnfs layout driver .mark_request_commit functions.

It marks all matching layout segments as NFS_LSEG_LAYOUTRETURN, which is an indicator for pnfs_put_lseg() to send layoutreturn, and also prevents pnfs_update_layout() from using the returning segments. Once it is set, it never gets cleared. It also sets proper io failure bit so that pnfs path can be retried after PNFS_LAYOUTGET_RETRY_TIMEOUT second.

Per RFC 5661 Errata 3208: | A client MAY always forget its layout state and associated | layout stateid at any time (See also section 12.5.5.1). | In such case, the client MUST use a non-layout stateid for the next | LAYOUTGET operation. This will signal the server that the client has | no more layouts on the file and its respective layout state can be | released before issuing a new layout in response to LAYOUTGET. In order to make such a signal unique to server, client needs to serialize all layoutgets using non-layout stateid. We implement this by serializing layoutgets when client has no layout segments at hand. Signed-off-by: NPeng Tao <tao.peng@primarydata.com> Signed-off-by: NTom Haynes <Thomas.Haynes@primarydata.com>

This reverts commit da788acb. That commit tried to fix the section mismatch warning by moving the ppc_corenet_clk_driver struct to init section. This is definitely wrong because the kernel would free the memories occupied by this struct after boot while this driver is still registered in the driver core. The kernel would panic when accessing this driver struct.
