I only got patches 2-4, but not patch 1. Sorry I have updated the way I send my patches, so each patch is sent regarding what is outputted by 'scripts/get_maintainer.pl' Patch 1 is https://lore.kernel.org/linux-arm-kernel/20220818203928.131059-2-cpe@outsight.tech/T/#md5d89721ac1861f31ca5d101ab9561371c35c904 Which has been sent to : Catalin Marinas / Will Deacon <will@kernel.org> And CC to : linux-arm-kernel@lists.infradead.org / linux-kernel@vger.kernel.org I will resend and force this patch to be sent to linux ML / Maintainer too.
