0.0.2i
	- Fix PKT_BUF_LIST error in fs/buffer.c
	- Fix pkt_find_dev in two spots, use q->queuedata in pkt_elevator_merge.
	- introduce pkt_make_request as READ remapper (and eventually add
	  block remapper for WRITEs too).
	- Loose READ/WRITE checks in pkt_elevator_merge and pkt_request, they
	  don't deal with anything but WRITEs after above change.
	- Fix pending request count in proc reading.
	- Fix increment usage bug for failed FMODE_WRITE opens.
	- Loose pd_lock/unlock, use io_request_lock for now. When block
	  switches to per-queue lock, a search/replace operation will be
	  sufficient.
	- Start to handle buffers non-uniform size buffers in a WRITE request.
	- Browse buffer cache hash table for possible bh victims
	- Fix blk_started_io to account buffers from buffer cache too
	- Do hole merging in regular elevator path
	- Fix bh_rq_in_between to look in the right direction
	- Remove sequencing from pkt_elevator
	- Use bh_cachep slab cache for private pool of buffer_heads
	- Remove old BH_Packet flag
	- Default udf to 2kB blocksize
	- Remove __getblk again
	- Remove rq->cmd checks in merge functions, only WRITEs now
	- Fix io_request_lock lockup when used with ATAPI (req->end_io)
	- Throttle down write when failed and retry, should write OPC
	  entry when this happens
	- Use current time for b_flushtime in buffer.c for packet device,
	  we don't want to postpone flushing a buffer if it causes read
	  gathering
	- Remove all bh->b_private references, we could be stomping on
	  other users (highmem, most notably).
	- Always use pkt_end_io_write as our bh->b_end_io callback
	- Added write caching config option (don't use yet)
	- Fixed missing brelse() for buffers stolen from buffer cache
	- Combine pkt_init_bh and pkt_recount_segments to only do one
	  scan of request (pkt_init_rq)
	- Fix dupe buffer_head in pkt_hole_merge
	- Change buffer_head sequence check in ll_rw_blk, add to SCSI
	  end_request handling
