The patch titled
md: simplify checking of available size when resizing an array
has been removed from the -mm tree. Its filename was

This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: md: simplify checking of available size when resizing an array
From: NeilBrown <neilb@xxxxxxx>
When "mdadm --grow --size=xxx" is used to resize an array (use more or less of
each device), we check the new siza against the available space in each
device.
We already have that number recorded in rdev->size, so calculating it is
pointless (and wrong in one obscure case).
