Subject: dm-raid: silence compiler warning on rebuilds_per_group.
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=3f6bbd3ffd7b733dd705e494663e5761aa2cb9c1;p=linux.git

dm-raid: silence compiler warning on rebuilds_per_group.

This doesn't really need to be initialised, but it doesn't hurt,
silences the compiler, and as it is a counter it makes sense for it to
start at zero.
