Move more pnfs-isms out of the generic commit code. Bugfixes: - filelayout_scan_commit_lists doesn't need to get/put the lseg. In fact since it is run under the inode->i_lock, the lseg_put() can deadlock. - Ensure that we distinguish between what needs to be done for commit-to-data server and what needs to be done for commit-to-MDS using the new flag PG_COMMIT_TO_DS. Otherwise we may end up calling put_lseg() on a bucket for a struct nfs_page that got written through the MDS. - Fix a case where we were using list_del() on an nfs_page->wb_list instead of list_del_init(). - filelayout_initiate_commit needs to call filelayout_commit_release on error instead of the mds_ops->rpc_release(). Otherwise it won't clear the commit lock. Cleanups: - Let the files layout manage the commit lists for the pNFS case. Don't expose stuff like pnfs_choose_commit_list, and the fact that the commit buckets hold references to the layout segment in common code. - Cast out the put_lseg() calls for the struct nfs_read/write_data->lseg into the pNFS layer from whence they came. - Let the pNFS layer manage the NFS_INO_PNFS_COMMIT bit.
