xa_get_mark

Name:xa_get_mark() - Inquire whether this mark is set on this entry.*@xa: XArray.*@index: Index of entry.*@mark: Mark number.* This function uses the RCU read lock, so the result may be out of date* by the time it returns

Proto:bool xa_get_mark(struct xarray *xa, unsigned long index, xa_mark_t mark)

Type:bool

Parameter:

Type	Parameter	Name
struct xarray *	xa
unsigned long	index
xa_mark_t	mark

XA_STATE() - Declare an XArray operation state.*@name: Name of this operation state (usually xas).*@array: Array to operate on.*@index: Initial index of interest.* Declare and initialise an xa_state on the stack.(xas, xa, index)

1745

_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

1746

entry = Starts a walk. If the @xas is already valid, we assume that it's on* the right path and just return where we've got to. If we're in an* error state, return NULL. If the index is outside the current scope

1747

When xas_get_mark() - Returns the state of this mark.*@xas: XArray operation state.*@mark: Mark number.* Return: true if the mark is set, false if the mark is clear or @xas* is in an error state. cycle

If Not Private Then Go to found

entry = xas_descend( & xas, Private )

1752

_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()
