The first patch makes session deserialization fail when file deserialization fails, instead of silently continuing with a partially restored session. The second patch (formerly patch 3 on the v1) initializes incoming FLB state before the finish pathdecrements its refcount, so the last-user cleanup path does not run from an uninitialized count. (and now utilises pr_warn instead of WARN_ON) Changes in v2: - drop the previous patch 2 after review - patch 2/2: replace WARN_ON(err) with pr_warn() in luo_flb_file_finish_one() Changes in v3: - patch 2/2. minor change to formatting. removed braces from scopped_guard Leo Timmins (2): liveupdate: propagate file deserialization failures liveupdate: initialize incoming FLB state before finish kernel/liveupdate/luo_flb.c | 19 ++++++++++++++++++- kernel/liveupdate/luo_session.c | 9 +++++++-- 2 files changed, 25 insertions(+), 3 deletions(-) base-commit: e3c33bc767b5512dbfec643a02abf58ce608f3b2 -- 2.53.0
