b57ff1303a pnfs: pass ds_commit_idx through the commit path 
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.

c220106fb4 nfs/filelayout: use pnfs_error_mark_layout_for_return 
Instead of calling layoutreturn directly, call pnfs_error_mark_layout_for_return
to mark layouts for return and let generic code return layout when
layout segments are freed.

f54bcf2ece pnfs: Prepare for flexfiles by pulling out common code

with the filelayout driver. This set of changes refactors
that common code out to avoid any module depenencies.
