Re: [PATCH 24/54] md/raid1: Improve another size determination in setup_conf()

Compare:

	foo = kmalloc(sizeof(*foo), GFP_KERNEL);

This says you are allocating enough space for foo.  It can be reviewed
by looking at one line.  If you change the type of foo it will still
work.

	foo = kmalloc(sizeof(struct whatever), GFP_KERNEL);

There isn't enough information to say if this is correct.  If you change
the type of foo then you have to update the allocation as well.

It's not a super common type of bug, but I see it occasionally.
