Pull probes fixes from Masami Hiramatsu:
- Protect kprobe_blacklist with RCU
RCU-protect kprobe_blacklist and use kfree_rcu() to prevent UAF races
during module unloading and enable safe atomic lookups.
- Fix multi-probe field use-after-free
Duplicate field and type strings on trace_probe_event to prevent UAF
when freeing primary probe
- Fix probe BTF member lookup:
Check the containing inner struct/union kflag when resolving
anonymous members to ensure correct bitfield offset calculation
Prevent unnamed bitfields from being pushed to anon_stack in
btf_find_struct_member(), avoiding false lookup errors
Fix code block indentation in get_bitoffset_of_field()
- uprobes error pointer safety
Guard free_trace_uprobe() with IS_ERR_OR_NULL() to avoid crashing
during automatic cleanup when an error pointer is returned
