Subject: [PATCH v2 0/5] list private v2 & luo flb v9

This series includes two separate workstreams. This is because FLB
should be applied on top of list_private, as it uses some of its
interfaces.

1. List private v2 (first 3 patches) Previous version:
https://lore.kernel.org/all/20251126185725.4164769-1-pasha.tatashin@soleen.com
For details, please read the cover letter from the previous submission.

v2 Changelog:
- Added a Reviewed-by from David Gow.

2. LUO FLB v9 (last 2 patches) Previous version:
https://lore.kernel.org/all/20251125225006.3722394-2-pasha.tatashin@soleen.com

v9 Changelog:
- Addressed suggestions from David Matlack and Pratyush Yadav: added
  booleans to track if an object was retrieved and/or finished.
- Modified the patches to use the list_private interfaces.

Pasha Tatashin (5):
  list: add primitives for private list manipulations
  list: add kunit test for private list primitives
  liveupdate: luo_file: Use private list
  liveupdate: luo_flb: Introduce File-Lifecycle-Bound global state
