Subject: [for-linus][PATCH 0/2] ftrace: Fixes for v6.18

ftrace fixes for v6.18:

- Fix regression of pid filtering of function graph tracer

  When the function graph tracer allowed multiple instances of
  graph tracing using subops, the filtering by pid broke.

  The ftrace_ops->private that was used for pid filtering wasn't
  updated on creation.

  The wrong function entry callback was used when pid filtering was
  enabled when the function graph tracer started, which meant that
  the pid filtering wasn't happening.

Shengming Hu (2):
      fgraph: Initialize ftrace_ops->private for function graph ops
      fgraph: Check ftrace_pids_enabled on registration for early filtering
