Meanwhile the issue addressed by this patch was fixed upstream with commit
877ba3f729fd ("ext4: fix potential htree corruption when growing large_dir directories").

The upstream patch was already cherry-picked to hirsute with "upstream stable
patchset 2021-08-30" [1] commit ffcc845ec245) and focal with "v5.4.140 upstream
stable release" [2] (commit 93ad4c3f59c6).

Therefore the SAUCE patch does not serve a purpose any longer and can be
either dropped or reverted.
