Subject: md: linear.c: Make two local variables sector-based.
X-Git-Tag: v2.6.28-rc1~288^2~7
X-Git-Url: https://openfabrics.org/gitweb/?a=commitdiff_plain;h=23242fbb470ff4c8c4d41f178832cf1929273d7d;p=~emulex%2Finfiniband.git

md: linear.c: Make two local variables sector-based.

This is a preparation for representing also the remaining fields of struct
linear_private_data as sectors.
