Subject: md/raid5: set reshape_position correctly when reshape starts.
X-Git-Tag: v2.6.31-rc6~83^2~2
X-Git-Url: https://openfabrics.org/gitweb/?a=commitdiff_plain;h=e516402c0d4fc02be4af9fa8c18954d4f9deb44e;p=~emulex%2Finfiniband.git

md/raid5: set reshape_position correctly when reshape starts.

As the internal reshape_progress counter is the main driver
for reshape, the fact that reshape_position sometimes starts with the
wrong value has minimal effect.  It is visible in sysfs and that
is all.
