Subject: Re: [PATCH] drm/tiny: pixpaper: Prevent inlining of send helpers to reduce stack usage

Hi Nathan, Jani,

Thanks for the detailed explanation.

Understood — if this only happens when CONFIG_KASAN_STACK is enabled
with clang, it doesn’t look like something that needs to be addressed in
the driver itself.

Thanks everyone for helping clarify this!

Best regards,
LiangCheng
