Re: runqslower build failed on Debian9

It has struct perf_ibs, which has a first field `struct pmu pmu` field with valid-looking size of 296 bytes, **but** the type that field points to is not a complete `struct pmu` definition, but rather just forward declaration. The way it is it shouldn't be even compilable, because forward declaration of a struct doesn't specify the size of a struct, so compiler should have rejected it. So it must be that either DWARF generated by compiler isn't correct, or there is DWARF -> BTF conversion bug somewhere. Are you using any special DWARF Kconfig settings? Maybe you can share your full .config and I might try to repro it on my machine. But either way, that warning you get is a valid one, it should be illegal to have non-pointer forward-declared struct as a type for a struct member. > > On 3/30/20 8:46 AM, Liu Yiding wrote: >> Something wrong with my smtp and this email missed. >> >> Send again. >> >> >> On 3/27/20 11:09 AM, Liu Yiding wrote: >>> Hi, Andrii. >>> >>> Thanks for your prompt reply! >>> >>> Please check attatchment for my_btf.bin. >>> >>> >>> On 3/27/20 4:28 AM, Andrii Nakryiko wrote: >>>> Would you be able to share BTF of vmlinux that is used to generate >>>> vmlinux.h?

[for-next][PATCH 02/21] selftest/ftrace: Fix function trigger test to handle trace not disabling the tracer

by Steven Rostedt

From: "Steven Rostedt (VMware)" <rostedt(a)goodmis.org> The ftrace selftest "ftrace - test for function traceon/off triggers" enables all events and reads the trace file. Now that the trace file does not disable tracing, and will attempt to continually read new data that is added, the selftest gets stuck reading the trace file. This is because the data added to the trace file will fill up quicker than the reading of it. By only enabling scheduling events, the read can keep up with the writes. Instead of enabling all events, only enable the scheduler events.
