Linus Torvalds b70100f2e6 Probes updates for v6.6:
- kprobes: use struct_size() for variable size kretprobe_instance
   data structure.
 
 - eprobe: Simplify trace_eprobe list iteration.
 
 - probe events: Data structure field access support on BTF argument.
   . Update BTF argument support on the functions in the kernel loadable
     modules (only loaded modules are supported).
   . Move generic BTF access function (search function prototype and get
     function parameters) to a separated file.
   . Add a function to search a member of data structure in BTF.
   . Support accessing BTF data structure member from probe args by
     C-like arrow('->') and dot('.') operators. e.g.
     't sched_switch next=next->pid vruntime=next->se.vruntime'
   . Support accessing BTF data structure member from $retval. e.g.
       'f getname_flags%return +0($retval->name):string'
   . Add string type checking if BTF type info is available.
     This will reject if user specify ":string" type for non "char
     pointer" type.
   . Automatically assume the fprobe event as a function return event
     if $retval is used.
 
 - selftests/ftrace: Add BTF data field access test cases.
 
 - Documentation: Update fprobe event example with BTF data field.

Pull probes updates from Masami Hiramatsu:

 - kprobes: use struct_size() for variable size kretprobe_instance data
   structure.

 - eprobe: Simplify trace_eprobe list iteration.

 - probe events: Data structure field access support on BTF argument.

     - Update BTF argument support on the functions in the kernel
       loadable modules (only loaded modules are supported).

     - Move generic BTF access function (search function prototype and
       get function parameters) to a separated file.

     - Add a function to search a member of data structure in BTF.

     - Support accessing BTF data structure member from probe args by
       C-like arrow('->') and dot('.') operators. e.g.
          't sched_switch next=next->pid vruntime=next->se.vruntime'

     - Support accessing BTF data structure member from $retval. e.g.
          'f getname_flags%return +0($retval->name):string'

     - Add string type checking if BTF type info is available. This will
       reject if user specify ":string" type for non "char pointer"
       type.

     - Automatically assume the fprobe event as a function return event
