This should allocate the blocks immediately instead of doing so during writeback. Further, will you be able to provide the perf data file along with kallsyms= or somthing similar that can be used to resolve the symbols. If not, the follo= wing output will also do: perf report --no-children --stdio -i perf.data Meanwhile I'll continue to look. Thanks! --=20 You may reply to this email to add a comment.
