sparse is not happy about this:

https://lore.kernel.org/r/202208140040.MMi4z6Ek-lkp@intel.com

That task_struct.sighand is marked __rcu and thus noderef and sparse
complains:

fs/exec.c:1307:26: sparse: sparse: incorrect type in argument 1 (different address spaces) @@     expected struct spinlock [usertype] *lock
+@@     got struct spinlock [noderef] __rcu * @@
