Name:pin_kill

Proto:void pin_kill(struct fs_pin *p)

Type:void

Parameter:

TypeParameterName
struct fs_pin *p
34  If Not p Then
35  _read_unlock() - marks the end of an RCU read-side critical section.* In most situations, rcu_read_unlock() is immune from deadlock.* However, in kernels built with CONFIG_RCU_BOOST, rcu_read_unlock()
36  Return
38  init_wait( & wait)
39  spin_lock_irq( & lock)
40  If Value is more likely to compile time(!done) Then
41  done = -1
42  spin_unlock_irq( & lock)
43  _read_unlock() - marks the end of an RCU read-side critical section.* In most situations, rcu_read_unlock() is immune from deadlock.* However, in kernels built with CONFIG_RCU_BOOST, rcu_read_unlock()
44  kill(p)
45  Return
47  If done > 0 Then
48  spin_unlock_irq( & lock)
49  _read_unlock() - marks the end of an RCU read-side critical section.* In most situations, rcu_read_unlock() is immune from deadlock.* However, in kernels built with CONFIG_RCU_BOOST, rcu_read_unlock()
50  Return
52  __add_wait_queue( & wait, & wait)

55  spin_unlock_irq( & lock)
56  _read_unlock() - marks the end of an RCU read-side critical section.* In most situations, rcu_read_unlock() is immune from deadlock.* However, in kernels built with CONFIG_RCU_BOOST, rcu_read_unlock()
57  schedule()
58  _read_lock() - mark the beginning of an RCU read-side critical section* When synchronize_rcu() is invoked on one CPU while other CPUs* are within RCU read-side critical sections, then the* synchronize_rcu() is guaranteed to block until after all the other
59  If Value is more likely to compile time(list_empty - tests whether a list is empty*@head: the list to test.) Then Break
62  spin_lock_irq( & lock)
63  If done > 0 Then
64  spin_unlock_irq( & lock)
65  Break
68  _read_unlock() - marks the end of an RCU read-side critical section.* In most situations, rcu_read_unlock() is immune from deadlock.* However, in kernels built with CONFIG_RCU_BOOST, rcu_read_unlock()
