Subject: Re: [PATCH v1] ext4: Remove deprecated noacl/nouser_xattr options

This patch[1] is needed on linux-5.15.y because the panic[2] is also found on
linux-5.15.y when debugging bug[3]. Back ported patch[4] is confirmed to fix
the bug on linux-5.15.y in the latest test of page[3]. Maybe back port on more
branches is needed per patch comments.
