SubjectRe: [patch 086/104] ext4: fix initialization of UNINIT bitmap blocks

Turns out this patch introduces a worse regression than it fixes. The
bug that the patches fixes is that on-line resizes of filesystems with
a 1k blocksize will usually fail. The regression is that when a
filesystem with 1k blocksize is stressed, the filesystem can get
corrupted. On balance, on-line resizing failing is less of a disaster
than corrupting the filesystem when its stressed. Fortunately, it's
only an issue when the filesystem blocksize is less than the page
size, which isn't the common case at least for the x86.

There are patches queued up to address this, but they haven't hit
mainline yet. Probably best to pull this from the stable tree for
now.
