Merge tag 'probes-fixes-v6.14' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace

Pull probes fixes from Masami Hiramatsu:

 - fprobe: remove fprobe_hlist_node when module unloading

   When a fprobe target module is removed, the fprobe_hlist_node should
   be removed from the fprobe's hash table to prevent reusing
   accidentally if another module is loaded at the same address.

 - fprobe: lock module while registering fprobe

   The module containing the function to be probeed is locked using a
   reference counter until the fprobe registration is complete, which
   prevents use after free.

 - fprobe-events: fix possible UAF on modules

   Basically as same as above, but in the fprobe-events layer we also
   need to get module reference counter when we find the tracepoint in
   the module.
