Subject: [PATCH] integrity: get rid of unneeded initializations in integrity_iint_cache entries

From: Jeff Layton <[email protected]>

The init_once routine memsets the whole object to 0, and then
explicitly sets some of the fields to 0 again. Just remove the explicit
initializations.

Hi Mimi,

I notice that this patch hasn't made the last couple of releases. Was it
dropped for some reason?

Thanks,
Jeff

Thanks for the reminder.  I accidentally dropped it (and Sascha
Hauer's patch).  The subject line is too long.  Assuming you don't
object, I'll replace the "get rid of" with "removed" and queue the
patch in the next-queued-testing branch.
