Hi Zigit, Thanks for sending this. It looks like the patches may have gotten split from the cover letter because the In-Reply-To header isn't exact for whatever reason (the two patches reply to <20240903130606.292935-1-...@iorw.io>, but the original has ID <62f5eea0b866e9e0+20240903130606.292935-1-...@iorw.io>). No worries for this initial rev, but just double check this if there is a v2 :) archive links of the individual patches for reference: [1/2]: https://lore.kernel.org/lkml/fd7d773099a0c7ec+20240903130606.292935-2-...@iorw.io/ [2/2]: https://lore.kernel.org/lkml/54fc087d02c52990+20240903130606.292935-3-...@iorw.io/ - Trevor
