[TFRC]: Add history query/lookup function
This completes the basic TX history functions that are implemented by this
patch set, by adding a lock-protected lookup function to look up the send
time of a particular sent packet.
I notice there is other functionality here also...
+/**
+ * tfrc_tx_hist_when - Retrieve send time of past packet
+ * If successful, it garbage-collects older (irrelevant) entries and returns 1.
+ */
+int tfrc_tx_hist_when(ktime_t *stamp, struct tfrc_tx_hist_head *head, u64 ackno)
+{
+
+ if (tail)
+ __tfrc_tx_hist_remove_tail(tail, head->cache);
+
Can you explain the rationale behind this?
