+/**
+ * __stack_depot_save - Save a stack trace to stack depot
+ *
+ * @entries: Pointer to the stack trace
+ * @nr_entries: Number of frames in the stack
+ * @alloc_flags: Allocation GFP flags
+ * @can_alloc: Allocate stack pools (increased chance of failure if false)
+ *
+ * Saves a stack trace from @entries array of size @nr_entries. If @can_alloc is
+ * %true, stack depot can replenish the stack pools in case no space is left
+ * (allocates using GFP flags of @alloc_flags). If @can_alloc is %false, avoids
+ * any allocations and fails if no space is left to store the stack trace.
+ *
+ * If the provided stack trace comes from the interrupt context, only the part
+ * up to the interrupt entry is saved.
+ *
+ * Context: Any context, but setting @can_alloc to %false is required if
+ * alloc_pages() cannot be used from the current context. Currently
+ * this is the case for contexts where neither %GFP_ATOMIC nor
+ * %GFP_NOWAIT can be used (NMI, raw_spin_lock).
+ *
+ * Return: Handle of the stack struct stored in depot, 0 on failure
