hi,
the rcu_dereference_check is defined as
#define rcu_dereference_check(p, c) \
__rcu_dereference_check((p), rcu_read_lock_held() || (c), __rcu)
so the caller does not need to specify rcu_read_lock_held()
condition.
Several places in kernel are spcifying rcu_read_lock_held as
rcu_dereference_check condition parameter. I separated them
into 3 patches:
1/3 - cgroup - removing superfluous rcu_read_lock_held check
2/3 - kernel,cred,kvm,security - removing superfluous rcu_read_lock_held check
3/3 - net - removing superfluous rcu_read_lock_held check
sry if I might missed or added somebody wrongly to recipients
wbr,
jirka
