Re: [PATCH v3] tracing/hist: bound synthetic-field strings with seq_buf

[Pengpeng Hou]

Hi Steve,

Thanks, I'll respin this.

I'll resend this with the tracing-style subject, add the clarifying
comment for `seq_buf_str()`, keep the `event_var` simplification out of
this patch, and move `saved_filter` back next to its point of use in
`create_field_var_hist()`.

Thanks,
Pengpeng
