Also create a commit_info structure to hold the bucket array and push it up from the lseg to the layout where it really belongs. While we are at it, fix a refcounting bug due to an (incorrect) implicit assumption that filelayout_scan_ds_commit_list always completely emptied the src list. This clarifies refcounting, removes the ugly find_only_write_lseg functions, and pushes the file layout commit code along on the path to supporting multiple lsegs.

Ensure that we conditionally drop the inode->i_lock when it is safe to do so in the commit loops. We do so after locking the nfs_page, but before removing it from the commit list. We can then use list_safe_reset_next to recover the loop after the lock is retaken. Signed-off-by: NTrond Myklebust <Trond.Myklebust@netapp.com>

- Fix a race in which NFS_I(inode)->commits_outstanding could potentially go to zero (triggering a call to nfs_commit_clear_lock()) before we're done sending out all the commit RPC calls. - If nfs_commitdata_alloc fails, there is no reason why we shouldn't try to send off all the commits-to-ds. - Simplify the error handling. - Change pnfs_commit_list() to always return either PNFS_ATTEMPTED or PNFS_NOT_ATTEMPTED.

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.
