  ext4: fix slab-use-after-free in ext4_es_insert_extent() (2023-08-27 11:27:13 -0400)

Note that there are a merge conflict with Cristoph's fs_holder_ops
patches.  The resolution is a bit complicated, but can be seen here:

The merge resolution can also be seen in the linux-next tree.

These changes were fully tested using "gce-xfstests -c ext4/all -g
auto", and there were no regressions.
