Here's an updated version of the pnfs-obj patches addressing Trond's
review comments from April 20.
I'm on my way to the airport so I'll get to see any comments
only tomorrow.
Benny
The changes in this version are:
* fix CB_NOTIFY_DEVICEID
* call pnfs_return_layout right before pnfs_destroy_layout
* remove assert_spin_locked from pnfs_clear_lseg_list
* remove wait parameter from the layoutreturn path.
* remove return_type field from nfs4_layoutreturn_args
* remove range from nfs4_layoutreturn_args
* no need to send layoutcommit from _pnfs_return_layout
* don't wait on sync layoutreturn
* get rid of PNFS_USE_RPC_CODE
* get rid of __nfs4_write_done_cb
* get rid of ds_[rw]size
* rename pnfs_{read,write}_done -> pnfs_ld_{read,write}_done
* reorganize and reorder the pnfs-obj patchset to expose dependencies
and separate api changes
* some cleaning up of the pnfs-obj patches
* add xdr space reservation for pnfs-obj opaque layoutreturn
and layoutcommit payloads
