get_tr_index

Name:In order to pass in both the trace_array descriptor as well as the index* to the flag that the trace option file represents, the trace_array* has a character array of trace_flags_index[], which holds the index* of the bit for the flag it represents

Proto:static void get_tr_index(void *data, struct trace_array **ptr, unsigned int *pindex)

Type:void

Parameter:

Type	Parameter	Name
void *	data
struct trace_array **	ptr	idx == &index[0]
unsigned int *	pindex

idx == &index[0] = container_of - cast a member of a structure out to the containing structure*@ptr: the pointer to the member.*@type: the type of the container struct this is embedded in.*@member: the name of the member within the struct.(data - * pindex, structtrace_array, trace_flags_index)
