Subject: [GIT PULL] probes: Fixes for v6.10-rc1

Hi Linus,

Probes fixes for v6.10-rc1:

- uprobes: prevent mutex_lock() under rcu_read_lock(). Recent changes moves
  uprobe_cpu_buffer preparation which involves mutex_lock(), under
  __uprobe_trace_func() which is called inside rcu_read_lock(). Fix it
  by moving uprobe_cpu_buffer preparation outside of __uprobe_trace_func().

- kprobe-events: Fix to handle the error case of btf_find_struct_member().
