linux.git/kernel/liveupdate/kho_block.c, branch master Linux kernel source tree kho: add support for linked-block serialization 2026-06-03T18:15:46+00:00 Pasha Tatashin pasha.tatashin@soleen.com 2026-06-03T15:43:56+00:00 0349ff2887059112ce06831ab29aec47a2a7285a Introduce a linked-block serialization mechanism for state handover. Previously, LUO used contiguous memory blocks for serializing sessions and files, which imposed limits on the total number of items that could be preserved across a live update. This commit adds the infrastructure for a more flexible, block-based approach where serialized data is stored in a chain of linked blocks. This is a generic KHO serialization block infrastructure that can be used by multiple subsystems.

Introduce a linked-block serialization mechanism for state handover.

Previously, LUO used contiguous memory blocks for serializing sessions
and files, which imposed limits on the total number of items that could
be preserved across a live update.

This commit adds the infrastructure for a more flexible, block-based
approach where serialized data is stored in a chain of linked blocks.
This is a generic KHO serialization block infrastructure that can be
used by multiple subsystems.
