Linus Torvalds 70a663205d Probes updates for v6.10: 
- tracing/probes: Adding new pseudo-types %pd and %pD support for dumping
   dentry name from 'struct dentry *' and file name from 'struct file *'.
 
 - uprobes: Some performance optimizations have been done.
  . Speed up the BPF uprobe event by delaying the fetching of the uprobe
    event arguments that are not used in BPF.
  . Avoid locking by speculatively checking whether uprobe event is valid.
  . Reduce lock contention by using read/write_lock instead of spinlock for
    uprobe list operation. This improved BPF uprobe benchmark result 43% on
    average.
 
 - rethook: Removes non-fatal warning messages when tracing stack from BPF
   and skip rcu_is_watching() validation in rethook if possible.
 
 - objpool: Optimizing objpool (which is used by kretprobes and fprobe as
   rethook backend storage) by inlining functions and avoid caching nr_cpu_ids
   because it is a const value.
 
 - fprobe: Add entry/exit callbacks types (code cleanup)
 - kprobes: Check ftrace was killed in kprobes if it uses ftrace.
