Greg, Per your request, here is a manual backport of the overlayfs fixes that were applied in v6.6.72 and reverted in v6.6.73. For the record, this overlayfs series from v6.7 [2] changes subtle internal semantics across overlayfs code, which are not detectable by build error and therefore are a backporting landmine. This is exactly what happened with the automatic apply of dependecy patch in v6.6.72. I will try to be extra diligent about review of auto backports below v6.7 from now on. Luckily, the leaked mount reference was caught by a vfs assertion and promptly reported by Ignat from Cloudflare team. Thanks! Amir.
