Name:The access to some variables in this macro is racy. We can't use atomic_t* here because all these variables are exported to debugfs. Some of them even* writeable. This is also the reason why a lock won't help much. But anyway,* the races are no big deal

Proto:static inline void dump_entry_trace(struct dma_debug_entry *entry)

Type:void

Parameter:

TypeParameterName
struct dma_debug_entry *entry
163  If entry Then
164  pr_warn("Mapped at:\n")
165  stack_trace_print - Print the entries in the stack trace*@entries: Pointer to storage array*@nr_entries: Number of entries in the storage array*@spaces: Number of leading spaces to print
