| |
Hi Reinette, Fenghua,
I've fixed the wording in changelogs and code comments throughout and clarified the explanations as Reinette had requested.
The patch series addresses the IPI race we discussed in the container move RFD thread[1]. The changelog in the patches should also provide a good description.
Updates in v4: - Reorder the patches so that justification for sending more IPIs can reference the patch fixing __rdtgroup_move_task(). - Correct tense of wording used in changelog and comments Updates in v3: - Split the handling of multi-task and single-task operations into separate patches, now that they're handled differently. - Clarify justification in the commit message, including moving some of it out of inline code comment. Updates in v2: - Following Reinette's suggestion: use task_call_func() for single task, IPI broadcast for group movements. - Rebased to v6.1-rc4
v1: https://lore.kernel.org/lkml/20221103141641.3055981-1-peternewman@google.com/ v2: https://lore.kernel.org/lkml/20221110135346.2209839-1-peternewman@google.com/ v3: https://lore.kernel.org/lkml/20221115141953.816851-1-peternewman@google.com/
Thanks! -Peter
