[patch 108/146] mm/migrate: remove redundant variables used in a for-loop

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Colin Ian King <colin.i.king@xxxxxxxxx>
Subject: mm/migrate: remove redundant variables used in a for-loop

The variable addr is being set and incremented in a for-loop but not
actually being used.  It is redundant and so addr and also variable start
can be removed.
