rcu_seq_state

Name:Return the state portion of a sequence number previously returned* by rcu_seq_snap() or rcu_seq_current().

Proto:static inline int rcu_seq_state(unsigned long s)

Type:int

Parameter:

unsigned long	s

41

Return s & RCU_SEQ_STATE_MASK

**Caller**
Name	Describe
check_init_srcu_struct	First-use initialization of statically allocated srcu_struct* structure
cleanup_srcu_struct	leanup_srcu_struct - deconstruct a sleep-RCU structure@ssp: structure to clean up. Must invoke this after you are finished using a given srcu_struct that* was initialized via init_srcu_struct(), else you leak memory.
srcu_gp_start	Start an SRCU grace period.
srcu_gp_end	Note the end of an SRCU grace period. Initiates callback invocation* and starts a new grace period if needed.* The ->srcu_cb_mutex acquisition does not protect any data, but* instead prevents more than one grace period from starting while we
srcu_funnel_gp_start	Funnel-locking scheme to scalably mediate many concurrent grace-period* requests
srcu_advance_state	Core SRCU state machine. Push state bits of ->srcu_gp_seq* to SRCU_STATE_SCAN2, and invoke srcu_gp_end() when scan has* completed in that state.
srcu_reschedule
rcu_gp_in_progress	Return true if an RCU grace period is in progress. The READ_ONCE()s* permit this function to be invoked without holding the root rcu_node* structure's ->lock, but of course results can be subject to change.
rcu_start_this_gp	_start_this_gp - Request the start of a particular grace period*@rnp_start: The leaf node of the CPU from which to start
rcu_advance_cbs_nowake	Move and classify callbacks, but only if doing so won't require* that the RCU grace-period kthread be awakened.
