Hi Eric-
Here are some that I can recall off the top of my head - I think this
catches them all:
commit 79c5d3ce614d8fe706545c7bca2158b63db6bb5e
Author: Li Zefan <lizf@xxxxxxxxxxxxxx>
Date: Mon May 11 15:06:46 2009 +0800
blktrace: from-sector redundant in trace_block_remap, cleanup
The last argument of block_remap prober is the original sector
before remap, so it should be 'from', not 'to'.

blktrace: correct remap names
This attempts to clarify names utilized during block I/O remap
operations (partition, volume manager). It correctly matches up the
/from/ information for both device & sector. This takes in the
concept
from Kosaki Motohiro and extends it to include better naming for the
"device_from" field.
