Subject: Re: [PATCH v4 04/19] liveupdate: Reference struct luo_file_set_ser via serialized pointer
Date: Wed, 11 Nov 2026 06:16:32 +0000 [thread overview]
Message-ID: <sashiko-outbox-208407@kernel.org> (raw)
In-Reply-To: <20261110050202.529473-5-tarunsahu@google.com>
> struct luo_session_ser currently embeds struct luo_file_set_ser directly
> by value. Embedding struct luo_file_set_ser couples the session layout's
> size and field offsets to struct luo_file_set_ser, preventing either
> structure from appending fields independently across kexec.
>
> Convert struct luo_session_ser to hold a DECLARE_KHOSER_PTR pointer to
> struct luo_file_set_ser instead of embedding it by value. Reserve space
> for both structures in each session block-set entry, placing struct
> luo_file_set_ser immediately after struct luo_session_ser, and bump
> LUO_ABI_COMPATIBLE from luo-v5 to luo-v6.
