Linus Torvalds acb7500801 runtime verifier fixes for v7.1:
- Fix reset ordering on per-task destruction
 
   Reset the task before dropping the slot instead of after, which was
   causing out-of-bound memory accesses.
 
 - Fix HA monitor synchronization and cleanup
 
   Ensure synchronous cleanup for HA monitors by running timer callbacks
   in RCU read-side critical sections and using synchronize_rcu() during
   destruction.
 
 - Avoid armed timers after tasks exit
 
   Add automatic cleanup for per-task HA monitors to prevent timers from
   firing after task exit.
 
 - Fix memory ordering for DA/HA monitors
 
   Fix race conditions during monitor start by using release-acquire
   semantics for the monitoring flag.
 
 - Fix initialization for DA/HA monitors
 
   Ensure monitors are not initialized relying on potentially corrupted
   state like the monitoring flag, that is not reset by all monitors type
   and may have an unknown state in monitors reusing the storage
   (per-task).
 
 - Fix memory safety in per-task and per-object monitors
 
   Prevent use-after-free and out-of-bounds access by synchronizing with
   in-flight tracepoint probes using tracepoint_synchronize_unregister()
   before freeing monitor storage or releasing task slots.
 
 - Adjust monitors for preemptible tracepoints
 
   Fix monitors that relied on tracepoints disabling preemption.
   Explicitly disable task migration when per-CPU monitors handle events
   to avoid accessing the wrong state and update the opid monitor logic.
 
 - Fix incorrect __user specifier usage
 
   Remove __user from a non-pointer variable in the extract_params()
   helper.
 
 - Fix bugs in the rv tool
 
   Ensure strings are NUL-terminated, fix substring matching in monitor
   searches, and improve cleanup and exit status handling.
 
 - Fix several bugs in rvgen
 
   Fix LTL literal stringification, subparsers' options handling, and
   suffix stripping in dot2k.
