From d386d59b7c1a39112ca875327339ed519df2b96c Mon Sep 17 00:00:00 2001 From: Wen Gu Date: Wed, 14 Aug 2024 21:08:26 +0800 Subject: net/smc: introduce statistics for allocated ringbufs of link group Currently we have the statistics on sndbuf/RMB sizes of all connections that have ever been on the link group, namely smc_stats_memsize. However these statistics are incremental and since the ringbufs of link group are allowed to be reused, we cannot know the actual allocated buffers through these. So here introduces the statistic on actual allocated ringbufs of the link group, it will be incremented when a new ringbuf is added into buf_list and decremented when it is deleted from buf_list.
