Type:void

Parameter:

TypeParameterName
struct nameidata *nd
803  fs = fs
805  If flags & RCU pathwalk mode; semi-internal Then
808  Do
809  seq = ad_seqcount_begin - begin a seq-read critical section*@s: pointer to seqcount_t* Returns: count to be passed to read_seqcount_retry* read_seqcount_begin opens a read critical section of the given seqcount
810  root = root
811  root_seq = __read_seqcount_begin - begin a seq-read critical section (without barrier)*@s: pointer to seqcount_t* Returns: count to be passed to read_seqcount_retry* __read_seqcount_begin is like read_seqcount_begin, but has no smp_rmb()* barrier
812  When ad_seqcount_retry - end a seq-read critical section*@s: pointer to seqcount_t*@start: count, from read_seqcount_begin* Returns: 1 if retry is required, else 0* read_seqcount_retry closes a read critical section of the given seqcount cycle
813  Else
