49 all RCU read-side critical sections currently executing have completed.
84 What locking restriction must RCU callbacks respect?
91 Permitting call_rcu() to immediately invoke its arguments breaks RCU,
92 even on a UP system. So do not do it! Even on a UP system, the RCU
101 preemptable RCU?
108 Because the calling function is scanning an RCU-protected linked
109 list, and is therefore within an RCU read-side critical section.
110 Therefore, the called function has been invoked within an RCU
114 What locking restriction must RCU callbacks respect?
116 Any lock that is acquired within an RCU callback must be acquired
118 For example, if "mylock" is acquired by an RCU callback, then
125 then, since RCU callbacks can be invoked from softirq context,
130 This restriction might seem gratuitous, since very few RCU
131 callbacks acquire locks directly. However, a great many RCU
