Revert "ext4: fix reserved cluster accounting at delayed write time"
This reverts commit d40e09f701cf7a44e595a558b067b2b4f67fbf87 which is
commit 0b02f4c0d6d9e2c611dfbdd4317193e9dca740e6 upstream.
Eric writes:
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.
