traced_probes ftrace: cap the per-cpu pages read per drain period This should limit the number of pages read from each per-cpu kernel buffer to the size of the kernel buffer (per drain period). See new comment on ReadTick for the full rationale of the read logic. + make ftrace reset logic set the buffers to a single page, zero is invalid (gets rejected) afaict.
