From: Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx>
This reverts commit 1ed1eef0551bebee8e56973ccd0900e3578edfb7 which is
commit 131294c35ed6f777bd4e79d42af13b5c41bf2775 upstream.

I recommend not backporting this patch or the other three
patches apparently intended to support it to 4.19 stable. All
these patches are related to ext4's bigalloc feature, which was
experimental as of 4.19 (expressly noted by contemporary
versions of e2fsprogs) and also suffered from a number of bugs.
A significant number of additional patches that were applied to
5.X kernels over time would have to be backported to 4.19 for
the patch below to function correctly. It's really not worth
doing that given bigalloc's experimental status as of 4.19 and
the very rare combination of the bigalloc and inline features.
