If you, or anyone else, feels it should not be added to the stable tree, please let stable@vger.kernel.org know about it.
Hey Sasha,
this patch is for the RAID stripe-tree feature marked as experimental, so I don't think it's needed to be backported, as noone should use it (apart from testing).
commit ec508a5930024b40064d70cb3dbdf856760cdf5d Author: Johannes Thumshirn johannes.thumshirn@wdc.com Date: Thu Sep 19 12:16:38 2024 +0200
btrfs: also add stripe entries for NOCOW writes [ Upstream commit 97f9782276fc9cb0de37a5eecb82204e48a5a612 ] NOCOW writes do not generate stripe_extent entries in the RAID stripe tree, as the RAID stripe-tree feature initially was designed with a zoned filesystem in mind and on a zoned filesystem, we do not allow NOCOW writes. But the RAID stripe-tree feature is independent from the zoned feature, so we must also do NOCOW writes for RAID stripe-tree filesystems.
