I found the branch does not have a fix [1] and it makes a conflict with [2/4]. Can you update it to merge the trace/fixes branch? [1] f35dbac69421 ("ring-buffer: Fix to update per-subbuf entries of persistent ring buffer") I can send a series on ring-buffer/for-next but I think it may cause the same conflict on git-pull later.
